According to science our universe has a beginning (search at “age of the universe” on pnas.org) and time is purely physical. Therefore there can be no such thing as time external to the physical universe. Timespace has a beginning.

It is a fundamental law of physics (causality) that every physical occurrence in the universe has a cause.
The fundamental laws of physics then require a cause of the universe ex nihilo (since timespace has a beginning); i.e., a Prime Cause Singularity that is non-dimensional and independent of timespace.

To conclude the above paragraphs:
Fact: No thing nor event in the known universe or laws of physics lacks a cause.
Assume: There is no Prime Cause (Creator / Singularity).
Ergo: There is no universe.
Fact: There is a universe.
Therefore: the statement that was assumed is proven to be a false statement by reduction ad absurdum (proof by disproof).
(Since "There is no Creator" is proven false, the opposite is true: There is a Creator.)

Being logically consistent (orderly), our (to say perfectly-orderly would be a tautology) orderly universe must mirror its Prime Cause / Singularity-Creator—Who must be Orderly; i.e. Perfect. An orderly—"not capricious," as Einstein put it—Creator (also implying Just), therefore, necessarily had an Intelligent Purpose in creating this universe and us within it and, being Just and Orderly, necessarily placed an explanation, a "Life's Instruction Manual," within the reach of His subjects—humankind.

It defies the orderliness (logic / mathematics) of both the universe and Perfection of its Creator to assert that humanity was (contrary to His Tor•âh′ , see below) without any means of rapproachment until millennia after the first couple in recorded history as well as millennia after Abraham, Moses and the prophets. Therefore, the Creator's "Life's Instruction Manual" has been available to man at least since the beginning of recorded history. The only enduring document of this kind is the Tor•âh′ —which, interestingly, translates to "Instruction" (not "law" as popularly alleged). (Source and further reading of how to relate to the Creator:  netzarim.co.il)

The fact that the Creator is perfect implies that He isn’t self-contradictory. Therefore any religion, and all religions contradicts each other (otherwise they would be identical), that contradicts Torah is the antithesis to the Creator.

Me too, Snert, I know there is a God.
