"Every solution to the equations of general relativity guarantees the existence of a singular boundary for space and time in the past."(Hawking, Penrose, Ellis) - 1970
Evidence Supporting the Big Bang
In the beginning God created the heavens and the earth. The earth was without form, and void; and darkness was on the face of the deep. And the Spirit of God was hovering over the face of the waters. Then God said, "Let there be light"; and there was light.

"The prediction of the standard model that the universe began to exist remains today as secure as ever—indeed, more secure, in light of the Borde-Guth-Vilenkin theorem and that prediction’s corroboration by the repeated and often imaginative attempts to falsify it. The person who believes that the universe began to exist remains solidly and comfortably within mainstream science." - William Lane Craig
Inflationary spacetimes are not past-complete - Borde-Guth-Vilenkin - 2003
Excerpt: inflationary models require physics other than inflation to describe the past boundary of the inflating region of spacetime.
"It is said that an argument is what convinces reasonable men and a proof is what it takes to convince even an unreasonable man. With the proof now in place, cosmologists can long longer hide behind the possibility of a past eternal universe. There is no escape, they have to face the problem of a cosmic beginning."
