(grin) I haven't met an atheist yet who didn't think so him/herself....ah, well.
I am actually agnostic, not atheist.
I simply don't like people confusing science with atheism, as some theists and all creationists tends to do with this stereotype.
I will l recognize any scientific work (as long as there are verifiable evidences), regardless if the scientists are theists, atheists, agnostics, deists or any other.
Despite what you might think of me, the Genesis is my favorite book in the entire Bible, but I don't treat the bible as work of science or work of history.
When I argue against creationists, I am actually arguing against their interpretations of the creation.
I have no desire to change the bible, to make it fit in the scientific paradigm, because I know that there are too many errors in the book (Genesis).
The bible is no more a science treatise than the Qur'an or the Book of Mormon (not that I have heard of any Mormons elevating BoM to the science podium).
Remember: the Big Bang was entitled that by Fred Hoyle, who remained a proponent of the steady state universe until the end of his life. He was making fun of the idea, and PART of the reason he did so was because he was afraid that some theists could use that theory to bolster their claim that God created the universe 'by a word,' or 'out of nothing."
Believe me, I am no fan of Fred Hoyle.
Personally, when dealing with science, the merits of any scientific theory is the number of verifiable evidences that support it, not atheism vs theism.
The more evidences FOR or AGAINST existing theory or a new hypothesis, respectively, the more probable or more improbable it is, not some idiotic personal preferences (like/dislike, atheism/theism, philosophy vs philosophy), which have no place in determining which theory or hypothesis is true or false.
I am serious, I don't give a crap about Hoyle being atheist. His Steady State model was debunked back in 1964, and should stay dead, until there are actually more evidences than the Big Bang.
Second, the Big Bang theory, originally called the expanding universe model, wasn't about atheism vs theism.
Georges Lemaitre was a Belgian Roman Catholic priest, as well as physicist. His priesthood meaning nothing to me, only his work in this expanding universe model. But what people tends to forget or ignore, was that he wasn't the only pioneers of the BB theory.
One Russian physicist Alexander Friedmann (1922) and one American physicist Howard Percy Robertson (1924-45) independently came up with similar theories, using Einstein's General Relativity as framework to construct their individual works. Both postulate the same theory, independently, and before Lemaître published Hypothesis Of The Primeval Atom in 1927.
It isn't important that Friedmann and Robertson are atheists, it is their work that was important. Likewise it was Lemaître's work that was important to science, not his religion or chosen belief.
Hoyle is stubborn idiot who let his ego to continue to push the debunked Steady State model. Although Lemaître was still alive at the time, Hoyle was actually competing against George Gamow, Ralph Alpher and Robert Herman, who wrote papers together in 1948, predicting the Primeval Nucleosynthesis (Gamow & Alpher partnership) and Cosmic Microwave Background Radiation (Alpher & Herman). These trio expanded Friedmann/Robertson/Lemaître model.
Gamow was also a Russian, who defected to the US, and he was former student of Friedmann. It was Friedmann's work that he based his work on, not Lemaître's. And Alpher was a former student of Gamow, before they worked together in 1948.
It was not long after their joint publication, that Hoyle tried to promote his own Steady State model in 1949, and it was on the radio show that he coined the name the Big Bang theory (supposedly during the radio interview), like you said as to mock it. Hoyle was idiot if he think the Big Bang is about theism, just because of Lemaître's involvement, because other contributors were mostly not theists.
It shouldn't matter if scientists are atheists or theists.
