Space is just about one of the most dangerous places humans have ever encountered.

Living on Earth is very much like the nursery, despite all of the natural disasters.

I believe that many will die in Space, because there is so very little room for error or negligence.

Man by his very nature is falible and negligent.
Man will not stay on Earth, that too is against our nature.

This point as with children learning to walk will never come again.
Then some will say, Oh how it all happened so fast!

Future humans with remember it all with nostalgia the way we remember flying through the air with only one propeller that kept us from crashing to the ground.
