I want you to be reassured that I don't hate you for your religion.
And I don't think you or any religious person is necessarily dumb.
We just happen to fundamentally disagree on certain points that seem to hold at least some value for both our lives.

And I will gladly admit that believing in god has the fundamental difference to believing in a flat earth that you described. The flat earth is soundly disproven and the existence of god is not.

I would in reply try to refine my point to saying that I think believing in god is comparable to believing in the easter bunny or the often quoted flying spaghetti monster (that I purposefully didn't want to invoke earlier).

Yes you are absolutely free to believe in any of those things.
I would fight to defend your right to believe in them.

But I cannot ever accept it as truth or even an educated opinion to hold without any proof pointing specifically towards the existence of any god.

And not to end on a negative note.
I love life around me, I love nature, I love animals.
I think the world is a wonder.

I do not believe any god made it the way it is.
I have no reason to believe that.
I just love it for itself.
