Honestly, I'm going to give an analogy my friend gave me in an example conversation, knowing I didn't believe in god. Its called the unicorn analogy.

We see horses all of the time. You my friends can touch a horse, photograph a horse, feel a horse, right? So you assume a horse exists.

Now, take a unicorn. You don't see unicorns walking around in the middle of the woods. At most you see someone put a birthday hat on a horse. So, you don't assume they exist.

God is like the unicorn.
