OK. Then why don't you set your own limits rather than believe in the limits set by some invisible man? Wouldn't you believe it more since you have justifications for your own decisions?
OK.
No. You should bother by evaluating how you can be purposeful for this world.
I know that it's not true cos it is unproven. I'd rather buy that bullshit than the bullshit that religion is spewing out.
You don't "know" it. You just blindly believe it in the hope that it is true and that you'll be rewarded in the end. You're unable to find a purpose for yourself on your own. Thus you choose the easy way out and find a purpose through religion. A purpose that is unproven.

Seriously, I'd definitely buy the 'people are just born when their parents decide to have sex' bullshit than the one you're trying to sell.
