Aren't scientists rather arrogant and elitist in abiogenetic theories?

Personally I've never been swayed by multiverse theories, EXCEPT if we say that our universe is a spatial universe, and any other universe would be a non-spatial one. Thus we can have the spatial universe we live in, and the universe of ideas that we think in, and there is no conflict between these concepts.

Not sure, but it might help to distinguish between determinism (secular) and predestination (religious).

I consider you to be an unversed being.
