user7149: Okay, I know that anything that come into existence has a cessation..
So, how did this world of suffering begin?
Or, if you say it never began and it's ever existent, why would it need to exist?
What's the cause that's made this material world?
If you say that the cause is the Karma of a being, how come Karma come into existence? (By existence, I mean to ask why does Karma exist?)
What's the ultimate cause or factor for existence or emergence of corporeality?
I'm not trying to argue or quarrel, but I'm searching for answers from the point of view of Buddhism.
I accept that these kind of questions and answers doesn't lead to cessation of pain or suffering, as the Buddha said, but I'm just eager to know :)

user-1: Ultimate reality isn't voidness, it has both the character of voidness and the character of things - in Shitou's terminology 'sameness' and 'difference'.
See his poem 'Sandokai': https://en.wikipedia.org/wiki/Sandokai

user-1: I will jump in and you can downvote if my answer is not suitable, I am not in a Buddhist tradition. But perhaps it offers something for the Asker, and maybe for others. It might not be part of the Cessation of Suffering as such, but when a question lodges in someone's awareness, often it is good to simply address it and move on. 
One of the leaders of a retreat I attended that I found helpful said, "The Void can't know itself." That is a statement to ponder. I find it to be useful. It speaks to the arising of Experience (all that we see) from non-experience. As I read the answers that were already posted, I realized something new. Andrei gave a very good answer that addressed the several questions of the Asker, and he said (if I may quote him) "The main condition for the world of suffering is ignorance. Particularly ignorance of Emptiness." As I read this, my thought was:
The Void knew nothing at the beginning, because there was nothing to know. So, "wishing" to know, it created Experience. But it could only proceed in ignorance, for every step of the way, it knew only what it had learned so far. Thus, Ignorance is unavoidable and inevitable at the start, and we must learn to overcome it.
I hope that this is a helpful contribution. Peace.

  cessation..

By creating everything.

Or, if you say it never began and it's ever existent, why would it
  need to exist? What's the cause that's made this material world?

Creation- Create 'objects' as relative to the 'subject'.

If you say that the cause is the Karma of a being, how come Karma come
  into existence? (By existence, I mean to ask why does Karma exist?)

It's relations.

What's the ultimate cause or factor for existence or emergence of
  corporeality?

Same reason used to create or emerge that gives feeling of existence. 

I'm not trying to argue or quarrel, but I'm searching for answers from
  the point of view of Buddhism.

In Buddhism main reason is 'Avijja' and the process is 'patichchasamuthpada'.

I accept that these kind of questions and answers doesn't lead to
  cessation of pain or suffering, as the Buddha said, but I'm just eager
  to know :)

By questioning can get rough idea of the solution. By practicing  the correct path will lead to cessation of creation(patichchsamuthpada).

user7141: About the beginning of Suffering
Here's the thing that you must understand.
There are certain things that Lord Buddha tried and ignored.One of which is the beginning.One like you Lord Buddha took interest in the matter and tried looking back at the beginning,i'm sure you know that lord Buddha's mind is the fastest.Lord Buddha looked back in time so long there is no number in our current number system to be given (that time is often given in a form of an idiom).Lord Buddha came to a conclusion in the end that the time itself is too far old,so old that it would be a huge waste of time to look back completely. Then Lord Buddha continued to add that the immense time he looked back is not even close to a Beginning,and said any normal being trying to reach the answer of this question would most likely end up going crazy.Lord Buddha instructed his followers to never try to find a beginning to the suffering,because it doesn't profit the way to nirvana and can't be reached.
About Karma
Karma is not a variable in physics.I know we talk about things like time coming to existence but the reality is unlike time karma does not need anything for it's existence.For example when Buddhism talk about destruction of this universe (Buddhism has explanations and predictions about the end of this universe and the new beginning),The human realm will have its destruction along with the destruction of Brahma and Deva realms,Even many hells will see the end.But a single hell would still be functioning (You see ,everything else is no more but karma still exists.) Buddhism describe Karma as nature (Like Temperature/Gravity) because it is how things happen (things need it but it doesn't need things).Because Karma is not a thing made of materials it is a function.

user254: One answer to the question "How did this material world come into existence" might be that the world comes into existence as a result of Pratītyasamutpāda.
Part of that theory is The Twelve Nidanas:

The Twelve Nidanas are a series of causal links that describe the process of samsaric rebirth and the arising of dukkha. In reverse order they also describe the way to liberation from samsara.[note 2] When certain conditions are present, they give rise to subsequent conditions, which in turn give rise to other conditions, resulting in the cyclical nature of life in Samsara.

The Twelve Nidanas include:


Ignorance      (Pali: Avijjā)
Mental fermentations/volitions       (Pali: Saṅkhāra Sanskrit: Saṃskāra)
Status consciousness     (Pali: Viññāṇa)
"Name" and "Form"        (Pali: Nāmarūpa)
The six senses       (Pali: Saḷāyatana)
Contact      (Pali: Phassa)
Feelings     (Pali: Vedanā)
Cravings/longings/desires        (Pali: Taṇhā)
Clinging to      (Pali: Upādāna)
Generation of factors for rebirth       (Pali: Bhava)
Birth       (Pali: Jāti)
All the sufferings


One point of view I think is that the world comes into existence because of birth.

user5000: Friend, you are asking the question of all questions.
Even if I would be explaining to you in eternity how this material world came into existence, you would not know how this material world came into existence.
Even if I used the most profound poetry of all the universe and you would be listening to this very same poetry in eternity, you would not know how this material world came into existence.
There are times when the mind is confused with research: "I'll try to find out how this material world came into existence." and the answer is never found.
There are times when the mind is confused with wrong view: "Oh I know how this material world came into existence!" and the answer is never found.
If I were to give you an answer, I would just confuse you. 
In confusion, you'll never find the answer to your question.
That's why the answer to your question must be silence. Nothing else but silence.
There is a path which will lead you to the answer you're seeking.
And what is this path?
It's the path leading to the cessation of suffering.
When suffering and its cause are fully known and this very same cause is removed, everything is known, even the answer to the question you're seeking.

user-1: Buddhism does not answer such questions, since they do not lead to Nibbana. The Buddha said himself, that he teaches only the cessation of suffering.
It's not that these questions are not important or interesting, they certainly are, but they will not lead one to Nibbana. They will only distract and agitate the mind, leaving it unfit for practice.
If you really want to know the answers to these questions, not only intellectually but experientially, then you have to become a fully enlightened Buddha (Sammāsambuddha). Then you will be able to know everything, that there is to know.
The questions you mention, fall under the "Four Imponderables (Acinteyyas)":

The four imponderables are identified in the Acintita Sutta, Anguttara Nikaya 4.77, as follows:
The Buddha-range of the Buddhas [i.e., the range of powers a Buddha develops as a result of becoming a Buddha];
The jhana-range of one absorbed in jhana [i.e., the range of powers that one may obtain while absorbed in jhana];
The [precise working out of the] results of kamma;
Speculation about [the origin, etc., of] the cosmos is an imponderable that is not to be speculated about.

These are questions that the Buddha did not answer. Only a fully enlightened Buddha can know the answer to these questions and the questions themselves.

user43: Looks like you misunderstand Shunyata (Voidness, Emptiness, Hollowness). Shunyata is not nothingness, it is lack of solidity. It is interdependence. Famous Zen teacher Thích Nhat Hanh coined a new term for this, "interbeing". In Emptiness, everything is relative, so there is no absolute reliable reference point you can measure everything against.
So the question of coming into existence is irrelevant. Existence and non-existence is a term that applies to individual phenomena. But in context of studying the true nature of things - Emptiness - individual phenomena are not truly individual - they are interdependently arisen and interdependently existing. They appear when their causes and conditions come together. They exist while their causes and conditions are together. They disappear when their causes and conditions go apart.
This world of suffering is a subjective world, a set of experiences, that arises in dependence on causes and conditions - just like any other phenomena. The main condition for the world of suffering is ignorance. Particularly ignorance of Emptiness.
The history and evolution of this material world is a subject of study in the fields of physics and astrophysics. This is not what Buddhism is about.
Karma is the chain of causes and effects, coming from beginningless times. Individual karma exists because of appropriation of these causes and effects as "I", "me", "mine".
The material cause of corporeality of living beings is a subject of study in the fields of biology and genetics. This is not what Buddhism is about. The phenomenal cause is self-identification with a living organism.
