I think it's funny how it looks like you are actually announcing your upcoming strawman.
"despite the facts, here's what I'll believe instead:"
No.
No.
Ok. I have about 20 "but's" and afterthoughts on that one, but I'll agree to it in general terms.
So 1 out of 3.
And none of them have anything to do with the "atheist perspective" which at bottom is just answering "no" to the question "do you believe in any gods?". Everything else that person
does believe, is separate from disbelief in theism. Just like it is separate from disbelief in bigfoot.
The things you
do believe determine your worldview. The things you don't believe are, at best, irrelevant.
You can't even strawman correctly.
Fact 3 could be true while 100% of people hold an irrational belief.
For most people to be rational
at most times, it means that all people have room for a few irrational beliefs as long as most of their beliefs and actions are rather rational.
When somebody is irrational
most of the time... they don't tend to last very long.
See, being irrational potentially has very fatal consequences.
If they would have the same beliefs, I would lump them together, yes.
But they don't have the same beliefs. Not even remotely.
So to say that "98% of people that ever lived had religious beliefs" is, while probably a true statement, evidence that there is something to those beliefs is
1. fallacious, it's the argument ad populum
2. imo dishonest. As it completely ignores the fact that those 98% are divided into many many mutually exclusive religions. 98% of believers aren't correct. They can't be. It's a false dichotomy in a way. It's pretending that it's either the 98% who are correct or the 2%. In reality, among those 98%, there are followers of sects that comprise only 0.00002%.
Additionally, you could also rephrase the question "why does 98% of people that ever lived hold religious beliefs?" into "why does 98% of people that ever lived hold
superstitious beliefs?".
Isn't atheism implying "all religious/spiritual people are wrong regarding religion and spirituality"?
