I'll say this colloquially and rhetorically (as I have little real interest in what the probably contorted answer might be), but I wonder how it can possibly account for the vast early period of time since the big bang when there was no consciousness.

Or was consciousness-created reality all made up on the spot on the birth of the first conscience?

And how has it been kept consistent through the life of all different consciences?

I think the simple fact that, for example, separated tribes of people have lived for millennium within a physically identical world is kinda a dead give-away that reality lives independently of consciousness.
