And no one here has denied the possibility of all this being true. What we question is the probability, and the reality.
Anything which is not clearly disallowed by the laws of physics is "possible", but that's an incredibly low bar to hurdle on the path to belief. You seem to think it's sufficient, but a large majority of posters here disagree with that. We could waste incredible amounts of time, energy and money believing in all sorts of things, if "possible" was our only criterion.
We only have some much time and treasure to spend in this life, so if you want us to believe something, you've got to come up with a better reason than just "possible".
And while you're at it, it wouldn't hurt if you could can the smug assumption that we're all just incapable of believing in something that is better than humanity. Try actually listening to what people are saying to you, and then crediting us with a little more nuanced system of understanding the Universe than you currently are ascribing to us.
