The Principle of Contingent Causation: The Impossibility of Infinite Regress.

[Belacqua]

There is no reason to posit any sort of First Cause UNTIL we have some data from the environment EXTERNAL to this universe. 
All you're doing is slapping a principle you think you know from a tiny part of this universe onto an environment you know absolutely nothing about.
There is no reason to consider ANY origin theories until there is data.

I understand that what you say is an inevitable conclusion from your metaphysical beliefs.

Those who hold to Neoplatonic, Vedantic, or Buddhist metaphysics disagree with you.
