I didn't downvote you. Just want to remind people that it isn't an absolute.

If we're not unique then it doesn't really matter if we wipe our species out. We'll just get chalked up to the great filter and some other species will do some archeology on Earth in the future.

I find the idea that we're unique much more interesting. If we are then we're effectively the guardians of the only intelligent life in the universe, and we should be doing a lot more to preserve it. Maybe there aren't treasures all over the universe. Maybe they're all here on our planet (and a few on the moon and Mars).
