I, for example, just love it when they claim that atheism is science.
Atheists claim that more and more about the natural world is discovered the more and more god's like Thor and Apollo get disproved. They give examples like lightening and evolution. Did you notice that since 1859 there has only been discoveries showing the other way. Isaac Newton said "Atheism is so senseless. When I look at the solar system, I see the earth at the right distance from the sun to receive the proper amounts of heat and light. This did not happen by chance." We have found so much more, Read the book
Rare Earth: Why Complex Life is Uncommon in the Universe to found out a little bit of just how much the universe is fine tuned. (Even Stephen Hawking and Steven Weinberg say the universe is "extremely fine tuned"). Also read "A formal test of the theory of universal common ancestry" by Douglas L. Theobald. It provides strong stastical data to support what is assumed already in science. The monophyly in life. All life occured only once on earth. So we have this super rare planet, and this super rare event happened... and only once.
Also atheists have forever denied the second premise of the KCM. After the proposal of the Big Bang (which was done by a priest btw) atheists nowadays have no choice but to deny the first premise. That something cannot come out of nothing. By denying this you are basically denying that we live in a lawful universe.
It's ok to be an atheist, just understand that it is the most irrational worldview.
Even the great Trey Parker agrees with me

"the silliest one I've ever heard is, 'Yeah ... there's this big giant universe and it's expanding, it's all gonna collapse on itself and we're all just here just 'cause ... just 'cause'. That, to me, is the most ridiculous explanation ever."
