What is a point? In geometry, what is a point?
I have seen Euclid's definition and definitions in some text books. Nowhere have I found a complete notion. And then I made a definition out from everything that I know regarding maths. Now, I need to know what I know is correct or not.
One book said, if we make a dot on a paper, it is a model for a point.
Another said it has no size. Another said, everybody knows what it is.Another said, if placed one after another makes a straight line.Another said, dimensionless.Another said, can not be seen by any means. 

My opinion can be argued, but a point is really just a starting or end place for an object. If we make the assumption that a point is real then it must be an intersection of two lines which in reality can be drawn in space. But two lines have to be created which they themselves begin as points and these collection of points extended out through space until somewhere at some place, these two lines will pass through one another and share just one common point between them. 
I really believe that it's all just mental construct and a way to connect dots.
