Atheism’s first problem is the simplest.
Why is there something rather than nothing?
The universe had a beginning. Science is clear on that.
Out of nothing, nothing comes.
So what caused the cosmos and set its laws in motion?
Atheism usually answers “We don’t know yet” or reaches for an unobservable multiverse. That’s not an explanation. It’s a hope that naturalism will someday save itself.
Logic points to an uncaused Cause outside of space and time.
