I read that page. It all sounds quite speculative at best. They say there are as many quantum theories as there are quantum scientists. Which one is right?

There is nothing about imaginary time being cyclic anyway mentioned on that wiki page, so you are just concocting silly theories to reject God.

Time as a spatial dimension doesn't change the fact if there was an infinite regress, you would have happened already, having had an eternity to do so. For example, this world didn't just come here from nothing. It had a cause. The north pole has a cause.

The article agrees with what I said, for it said, "But when visualized with imaginary time, the singularity is removed and the Big Bang functions like any other point in spacetime."

So a cause is needed. Time can't just come into being from nothing.
