Here's a quote from Richard Dawkins, probably the most famous atheist, in his book, The God Delusion.
The God of the Old Testament is arguably the most unpleasant character in all fiction.
Jealous and proud of it, a petty, unjust, unforgiving control freak,
a vindictive, bloodthirsty ethnic cleanser, a misogynistic, homophobic, racist, infanticidal, genocidal,
filicidal, pestilential, megalomaniacal, sadomasochistic, capriciously malevolent bully.
Yeah, but you didn't give evidence that he's not real.
Right? You got a problem with all of his laws, but where's your evidence in this book?
You don't have any logical arguments. All you're saying is, I don't like the God of the Old Testament,
therefore he must not be real.
Well, that's not a very good argument to prove that there is no God.
It's just called, you don't like the laws of the Bible.
And you know what it does? It actually confirms the word of God that says they hold the truth in unrighteousness, doesn't it?
I mean, you're just proving the Bible.
So that's what you think of God?
Yeah.
