Personally I think the possibility is there that our known cosmos is teeming with life. Looking at tardigrades on earth I even think the possibility of micro bacterial life that exists in space itself is even possible.
But the resounding utter facts to date is there is not a single thing. There is a lot of hope, a lot of want, a lot of belief.
But would it not make sense if it is true to put species so far apart they can barely see each other let alone ever meet each other.
If there is an alien race or races out there then they will be busy with their own anthills and their own bacteria in thermal vents etc. They also may have telescopes but probably and hopefully perhaps, are forever restricted by sheer scale and distance they will never have a chance to visit.
Even if like us we are already looking at the real possibility of exploring our solar system in the next 100 years.
Wright brothers flew in 1903
Perhaps 2103 will see manned Jupiter missions from established Lunar and Mars bases.
But the ask to find a neighbour.
The hubble Deep field image was astounding and the numbers are so large that almost surely yes there must be another race out there with car insurance, bills, mortgages, and kids who are dicks!
But the distance and scale is so vast so enormous. It stops us from fighting and messing up the beauty of it all.
Contact
Is probably my fav space alien contact type movie ever. I love it.
Although I do like a good alien invasion film or game.
