It’s easy to say “we’re just separated by time and space” but that discounts why there’s no evidence of current or past life even somewhere close like Mars, where life on Earth formed after the formation of Mars. Why can’t we find simple cell fossils?
It could be that life formation is a slow process, or rare process, so that means intelligent life may be even rarer. To me that means every wasted human life and potential is a crime on a cosmic level. The most precious commodity in the universe may be the human brain, as far as we know.
If there is another intelligent species that develops space travel, then we better hope to God that they’re woke otherwise why wouldn’t we logically expect them to do to us what we do to cows or chickens.
