Men's destiny is:
STAR TREK
Nothing seems to last forever -and our Sun and Mother Earth surely wont- but if man will find a way to travel through space and find other suitable planets men will have a way to survive in the long run. This includes altering our beings by technical means.
I fear for cloning and powerful AI, and such, but that's because I am still divided between history and future.
I somehow believe God is revealing to us all the time. That includes all technical knowledge science literally discovers.
We have to put it to good use in the interest of mankind. That is all that matters.
So maybe we are heading for Star Trek. And forget the Klingons and whatever
But who knows: Other life elswhere. Anything is possible.
