Seems like it would err on the side of “maybe something exists” which doesn’t quite feel like a middle ground.
Replace UFOs with Sasquatch.
“Sasquatch exists and here is the picture and Sasquatch tracks to prove it!”
“You made that up. It’s a guy in a costume. Why can’t we find any single dead Sasquatch? Why are all the pictures and videos crappy?”
“Why can’t you meet me in the middle and at least admit it’s possible that Sasquatch exists??”
Personally I’m open-minded and find the topic of aliens quite interesting. But there isn’t a single ounce of convincing evidence and it would require a gigantic coverup with tons of complicit actors. There needs to be extraordinary evidence before anyone needs to agree to meet anywhere in the middle. Until then we should default toward it not existing. In other words, your null hypothesis is that it doesn’t exist. So far the evidence has failed to cause someone to reject that hypothesis.
