I think first of all, Halfie would have to explain why he thinks these are 'atheistic' myths?
Atheists are a very small fraction of the population. Nowhere near enough people or with enough clout to swing the consensus of any branch of science one way or another just based on ideology.
So, cosmology, biology, geology, all have mainstream theories that are accepted by the experts, whether those experts are atheists or theists, BECAUSE THEY HAVE EXAMINED THE EVIDENCE FOR THE CLAIMS.
The professional theists just don't try to use 'gods' in their examination and explanation of 'What Happened.'
And the professional atheists don't go home at night and ponder how a new discovery fits into their theology.
So, to expose an atheist myth, Halfie would first have to IDENTIFY an atheist myth.
"Science which can be explained without invoking a skybeast" is not atheistic. It's just 'science.'
And halfie lacks the chops to actually disprove science. He's yet to show that he even understands it.
That is where you have it wrong. Science has never proven that no God is required. They have merely said, "We can't tell if God exists." There's a subtle difference, Keith. It is my belief that none of this stuff you guys study would even be possible without God. Science just assume it's possible without God. But, assumptions are not proof. They are beliefs, just like my belief.
Wrong again. While science can say nothing about the supernatural, it can be used to test for the effects of the supernatural on our everyday lives. To date, pertaining to any area that has been the subject of scientific inquiry, science has never concluded that a phenomenon has to have a supernatural origin. Never! Not in a single instance! In other words, if your god exists, it is powerless to have any perceptible effect on our lives. Which would be exactly like a god that doesn't exist.
Ignorance can be cured. But you have to be willing to work at it.
It's worse than that for fans of the supernatural.
One of the interesting things that has fallen out of the Standard Model is that we have determined every possible interaction with matter, between a very broad range of energies. There are no unknown forces - if there were, they would have a corresponding particle, and it would have been detected by the LHC and other particle accelerators.
The ONLY unknown forces that might exist would either need to be very long-range (the graviton, for example, might exist; But it's influence is irrelevant on human scales - that is, you cannot use gravity to have an influence on a specific person in a crowd, much less to influence a specific neuron or group of neurons. So gravity isn't a possible way for a hypothetical god to place visions in the mind of a prophet, or for a hypothetical soul to be transmitted to the supernatural realm on a person's death); Or very short range - perhaps there's a force that can subtly influence quarks, that we haven't yet detected, but if so, it would have no discernible influence on an object as large as a molecule, unless so much energy was used that the resulting explosion could level a city. Humans probably can't survive a divine intervention that is that energetic.
Science hasn't disproven gods in general. But it has disproven gods that interact on scales bigger than atomic nuclei, but smaller than solar systems. And as almost all of religion is interested in the influence of god(s) on Earth and its inhabitants, science has disproven all of those parts of every god hypothesis.
There's no way to eliminate the "god of the gaps"; But the remaing gaps mean that we can eliminate, and have eliminated, gods that have any direct influence on humanity.
A deist god, that crafted a universe in extreme conditions, and has had no influence on that universe since, could still be posited without absolute certainty that it is false. But any god that hears (much less answers) prayers; any soul, or supernatural influence on our physical bodies or brains; any afterlife (or pre-birth existence of personality or "self"); all these things have been ruled out by physics.
It's over. Fortunately for the theists, the vast majority of humans don't know or understand Quantum Field Theory. But ignorance doesn't make things untrue; and it is undeniably true that QFT rules out the vast majority of the gods that humans have ever developed.
And QFT could be wrong; But only in the same sense that the Moon could be made of green cheese. It's possible that there's a massive error in QFT, and it's possible that the Apollo missions just happened to miss the outcrops of Stilton at the edge of the Sea of Tranquility.
Actually, given the relative stringency of the tests done, and the accuracy of the results, it's considerably more plausible that the Moon is made from dairy products than it is that QFT is sufficiently wrong to permit the existence of an unknown force at human scales.
There are only four forces at our scale. All four are easy to detect. If a soul or god were using any of these to affect humans, we would have detected it long ago. And as humans are made of matter, any influence that doesn't affect matter isn't relevant. So 'Dark energy' or 'Dark matter' don't help the theistic case - unless their god is only interested in objects the size of galaxies.
So not only have we never detected any supernatural influences on reality; We have positively ruled out any possibility that such influences could exist.
