Here's a "lucky" coincidence...
Out of my dad's millions of little "squigily, squirmy, sperms" one in particular made it to my mom's egg at the right time of the month, in the right year, month, day, hour, etc. for me to be concieved.
Had they not met, I wouldn't be here. Had it been a month later, a different egg would have meant a different person. Had a different sperm fertilized the egg, I wouldn't be here. What are those odds???? I'm "lucky" to be here I guess.
Then if you go back... what were the chances of each of their parents meeting and producing them... what about my grandparents? We have a whole family history of the odds of these two people meeting and having their children.
Keep going back. The odds mount to an impossible set of "lucky" coincidences that we were even born. Crazy. Yet there are billions of us walking around, despite the odds of our individual self being here.
So the odds of all life are infinitesimal - immeasurable, but it happened. What are the odds that a "creator" exists out of nowhere (no explaination there) and made everything? What are you saying, that a powerful, intelligent being can exist without a creator? Hmmmm, I believe I'm saying the same thing. We humans, animals, life, universe, exist "out of nothing", and I believe in it.
