Practically the existence of other extraterrestrial life forms can't really affect humanity that much.The closest star is over 4 light years away. I doubt communication would be very successful with a 4 year gap between any response. Any physical travel would be incomparably slow, so I doubt any life form would be able to intentionally visit Earth. So we are pretty much limited to searching for life in our solar system.
