Very worthy accomplishments. However, these didn't just occur out of thin air. For example, the mathematics required to put a man on the moon wouldn't have been possible without the invention of Hindu-Arabic numerals, automobiles wouldn't have been possible without the invention of the wheel in Mesopotamia over 5000 years ago etc. It's a great big daisy chain with all links being important. Lose a link and you may not have come this far along. We're all in this together.
