This is a short post, because I can’t embed the video – so I’m just going to post the link to the Lightsource web site which has the video.
Here’s a web page from Caltech that goes over 3 of the 6 evidences for the Big Bang.
Excerpt:
Three main observational results over the past century led astronomers to become certain that the universe began with the big bang. First, they found out that the universe is expanding—meaning that the separations between galaxies are becoming larger and larger. This led them to deduce that everything used to be extremely close together before some kind of explosion. Second, the big bang perfectly explains the abundance of helium and other nuclei like deuterium (an isotope of hydrogen) in the universe. A hot, dense, and expanding environment at the beginning could produce these nuclei in the abundance we observe today. Third, astronomers could actually observe the cosmic background radiation—the afterglow of the explosion—from every direction in the universe. This last evidence so conclusively confirmed the theory of the universe’s beginning that Stephen Hawking said, “It is the discovery of the century, if not of all time.”
The article explains all three evidences in detail. It is important to show atheists how the progress of science has dashed their hopes for an eternal, uncaused universe. One discovery – that could be reversed. Two discoveries – that’s conclusive. Three – discoveries – that’s an open and shut case. (And there are three more discoveries not mentioned in the article – the second law of thermodynamics, radioactive element abundances and the stellar lifecycle itself).
And, of course, William Lane Craig uses this scientific evidence in his kalam cosmological argument, which is described in a peer-reviewed paper from this Astrophysics journal.

As I understand it, the astronomers were reluctant to accept the theory. They doubted it not because of scientific evidence but because of the metaphysical implications: if the Universe was not eternal, then where did it come from? The theory bore too much resemblance to the Creation “myth” of Genesis. Being good scientists, they tried as hard as they could to disprove the whole idea but in the end the evidence was too convincing. This led to a crisis that has finally been solved by the great scientist (but not so great a philosopher) Stephen Hawking. He simply explains that the Universe popped into being out of…….nothing! For many years biologists have laughed at the Medieval “scientific” claim of spontaneous generation of life. Insects literally coming to life in the mud spontaneously from nothing. Oh, how wrong we were to laugh. Now we know that not only can insects arise from nothing, but whole Universes can come into being without even the need for mud!

It isn’t really possible to be a great scientist without first being a great philosopher. Stephen Hawking has clearly demonstrated that with his latest work “The Grand Design”. What is the point able to have all the data in the world available to one if one is incapable of correctly interpreting it? And how is it possible to correctly interpret any scientific data if one believes in self-creating things – even universes? Hahahahahahahahah!
