Indeed, the more recent discoveries of just how finely tuned our universe is, the more astonishing in how it looks orchestrated by a super intellect. There are only four forces, remarkably, that built and regulate our universe (gravity, electromagnetism, strong, weak). But their respective strengths are extremely critical to make things work at all. For example, a very tiny increase in the strength of gravity would have crushed the universe in its early seconds. A tiny decrease would prevent stars from forming.
Atheists were quick to reject Lemaitre's "Primeaval Atom" model -- the science that presented what we call the BBT. They were set on the view, as was Einstein originally, that the universe was static (fixed for eternity) and infinite. A "beginning" pointed directly to the first words of the Bible. To top it off, Lemaitre was a priest. But the evidence kept growing and science respects the scientific method, which kept revealing just how wonderous BBT truly is. There is no real competition to BBT, currently.
