So, I feel like the only time I come on here is to ask you guys for advice or to help me with some sort of problem pertaining to something I don't know, but could I get something verified? 
So, my mom, aunt, their husbands, and all of their kids (excluding me) are Muslims. I've tried debating them a few times, and every time, they always bring up this thing about how some guy knew exactly how a baby formed in the womb (trimesters, developmental stages, etc.) and how NO ONE could have POSSIBLY knew that at that time. This is their basis for believing in Islam. (Also I should include how they both live in countries where if you denounce Islam or say you don't believe in it, they can basically put you to death. But, that's a different story)
I don't really know how valid this is or if it's even true, just looking for some validity because I can't seem to find anything about it online. You guys seem to know all about this stuff
