There’s been no real proof that aliens exist. I wholeheartedly believed that aliens existed and that UFO’s were spacecraft from another planet up until about 20 years ago. I saw all the photos and all the evidence. But I eventually became a skeptic after I saw every piece of supposedly " increnvertible" evidence debunked and proven to be a hoax. Just because the universe is supposedly infinite does not mean without a doubt that there is alien life out there. That is not the best argument for alien life out there. Of course I don’t have all the answers, there may be other life out there, there may not. But so far, we have no solid proof.
