probability says there out there. I can agree with that. BUT, probability also says that the chances of earth being visited 0. It takes 150,000 years for light to travel from one end of our galaxy to the other. And the milky way is just one of atleast 500 BILLION galaxies. but y'all wanna believe that aliens can make that trip multiple times a year, every year, since whenever the first UFO sighting was.
Ask yourself this, if you had the impossible technology to travel these vast distances WHY would you do it. To cut up some cows? make pretty pictures in wheat fields? flash your sweet parking lights in the sky for a few minutes and then roll out?
sh*t, even us with the little technology we have don't actually go visit mars ourselves, we build robots to do it for us.
I think everybody is so busy trying to prove weather something is or isn't, that they forget to ask the bigger question. "Why would that make sense even if it was possible"
when r probabbilities ever 0??? that would make it a certainty lol...ur basing ur theory on the time n energy required to travel places on earth. fact is we have no clue what technology other planets could have, if they r millions of years beyond us then who knows....it takes 3 years to get to mars with the tech we have now, the human body can not withstand 3 years in space because it was designed to be in a atomosphered environment. thats why we have yet to send man to mars.
Now the thing u said that rlly shocked me was that it wouldnt make sense if it was possible, or u asked why it would make sense? Why did humans branch out from africa? 2 main reasons...
1) The need to avoid conflict for resources. rather than go to war with another tribe over food and water, early humans would migrate to unpopulated areas to set up their own "colonies"
2) CURIOSITY Its in all of us some more than others, the need to know things. whats over that ridge, under that water, and in their case across that galaxy
Now is it not believable that aliens been going thru the universe looking to explore, as we would if we could, and also maybe to collect resources they may need (more far fetched im aware but plausible u must agree on that)
