I’m 100% sure they exist and I’m 99.9% sure there won’t be any contact over the next 10 years. It’s entirely possible there will never be, though I do hope otherwise.
I believe that it is very likely that life exists elsewhere it the universe, but it ist very statistically unlikely for us to meet during the timeframe of our species existence. Even more so in the next 10 years. Tho an analysis of Europa might prove me wrong.
So I believe in aliens only in a statistical sense. There is a lot of space out there so SOMETHING has to be elsewhere. But those same stats tell me that the odds of it being intelligent is low, intelligent enough to contact us very low, existing at the same time as us (since we are a blip in the history of the universe) astronomically low and having the ability, or desire, to travel to us hilariously, laughably, insanely low.
I don’t think people who say aliens have been to earth are serious people. Sorry.
Grey aliens are us in the future
The universe is so unimaginable large and there are so many stars and planets that there are good chances of the existence of extra terrestrial life, but at same time there is a very small chance that they can find us, even if they are advanced enough to search for life in the universe. If they are much more advanced than us they probably don’t care, in the same way we don’t care to try to make contact with all the ants of the earth.
Dunno but if I were an alien the stupidest thing I could do would be contact “humans”.
