If youre interested, here is my basis for belief. Its a Carl Sagan philosophy that goes something like this...
"I have an invisible dragon in my garage. You cant touch it, you cant see it, you cant smell it, you cant hear it or otherwise detect it with any instrument, but it is real."
Do you believe me? Of course not. You werent raised to believe in my invisible dragon. All of us have an innate bullshit detector, and the more extreme the claim is, the more extreme the evidence needs to be in order to convince us. If someone tells you that they ate eggs for breakfast, you are likely going to take them at their word, but if they tell you they have an invisible dragon in their garage, you will require a shit ton of evidence before you believe it.
You and I both agree that all other religions on Earth besides yours are false, but I just take it one logical step further and apply the same standard to your religion too.
