There have been thousands in the past. Which one is the "real" one that exists?

There's only one, because there can only be one source and center of all things, the "thousands" in the past have never been, they're just products of people trying to make sense of things.

Plus, I do believe that even though the source and center is only the one, he has many facets, and even though there's only one God, there are many deities, who run this universe.

You're just a simplistic mind, who looks at the state of religion, find it wanting and then throw the baby out with the bath water.

And whatever the average "scientist" knows is irrelevant, if your initial assumption is wrong, everything else will also be, and the initial assumption required to be part of that club nowadays is, there is no God.

If they assumed there is God, and everything flows from him and through him, they'd look at all matter and energy in a totally different way, instead of dreaming up magical particles out of thin air to try and make sense of things they can't possibly understand.

Btw these "scientists" you worship, are in the same club of all the ones that are strongly behind the Covid BS.
