So by some estimates... we came very, very close to not even becoming an existence and only by chance -a VERY, very lucky chance, did events work out so that we might someday populate our world?
Hard to believe only chance had a hand in that, no?
If one contemplates all the things that had to go just right for us to be here, it is amazing that we are here. Intelligent life is a rare, possibly unique thing in our universe. I think we will discover that simple life forms are fairly common. Higher life forms not so much.
