Even if this does point to some higher being or reality, it isn't necessarily any conception of God. Also, true randomness in fluctuations in quantum fields could refute 2, no? Also, trying to extend the notion of time to some point at infinity in the past, as if this is a proof by induction, is absurd. Mathematics are free for us to make statements about because we can start with whichever axioms we like. However, our realities (plural) are necessarily constrained by what we think and observe. There is no way to be certain of the nature of one's reality without somehow transcending it.
