This entire argument proves only one thing that I can think of; that there are a lot of unanswered questions. Reading the OP link only proved this author had nothing more than an algebraic understanding of physics and cosmology. Which frankly is fine and more than most people, but the extrapolation to objectively deny the concept of a singularity based universal origin is just completely false. There is no objective proof of the beginning (or if there was a beginning) to be had. It makes far more sense to acknowledge what we are uncertain about and then find ways of becoming certain.
My religion is the understanding of my world. My god is the energy that underlies it all. My worship is my constant endeavor to unravel the mysteries of my religion.
