I still didn't read it all as promised, but I did say this was already up my alley.
If the universe is infinite and, so is time, than anything that can possibly happen has already happened.
If that is so, then we have already been alive, living this one, countless times.
If not, then why is there anything at all? Absolute zero is a perfect number and makes the most sense.
That sums up my thoughts on it in as few words as possible.
One thing is for sure, given what we know. There HAS to be other intelligent life out there given the magnitude of the universe and the odds. They may have different names for atoms and have a different periodic scale, but we are all speaking the same universal language and trying to figure this all out through objective cause and effect which never lies.
We should welcome our alien cousins, but they probably look at us as primitive apes who can't even accept ourselves, going to war, and flinging poo, and other weapons we have mustered. A drone is just an advanced form of flinging poo and claiming territory and dominance.
