It sounds like you are confirming my point when I said:We differ in some parts. I agree that in order for Sasquatch to be believable, it must be actual, not imagined. That's what I said earlier, that I don't believe in Sasquatch's actuality.
Where we differ is here: in order for things to exist, they must be. There are no other requirements for that word. To exist is to be. Actual things are. Imagined things are. Phyiscal things are. Theoretical things are. Each adjective doesn't create a whole new thing--they all exemplify "being." The canvas is wide.
If you want evidence, it's right there in our language. You claim that imagined things don't exist, but things exist in our imagination
"Sasquatch may exist in someone’s imagination, but because he doesn’t have a physical existence, he doesn’t exist actually or in reality. Do you agree?"
I think we agree much more than we disagree concerning the Sasquatch scenario. Now getting back to God; when someone says they believe in God, what they really mean is that they believe in God's actuality; is this your position?
