It is an either/or argument. Either there is a god, or gods, or not. If not, then there is no intelligent guidance behind the emergence of intelligent life on this little speck of dust we call Earth.
Sure, it's possible that natural selection led to human civilization all by itself. It's also possible that human beings are not the apex of evolution. It's quite possible that intelligence will become an evolutionary dead end.
It's also possible that there is some purpose behind it all. Science can not prove that either or argument one way or another. Yes, evolution and natural selection shows how live came to be the way it is. it does nothing to show why.
Or, is there no reason? Is there no meaning to life? Do we just live for a while, then die, then there is nothing? One day, humans will die out, and intelligent life will be over, nothing left but an uncaring universe? How do you know?
Maybe that is how it is. If so, then mankind does not matter. My life and yours does not matter. One day, we will be gone, and no one will be left to care. Maybe I don't believe that because it is too hard to accept, but there is no scientific proof either way.
One day, the sun goes nova, the Earth is no more than a dust mote that has drifted into a campfire, and it's over. No one is left to know or care.
If intelligent life did not perceive the universe, would it still exist?
