So who was the first person's mother and father? A sperm cell doesn't show up out of nowhere, does it? And a uterus doesn't just exist for no reason, does it? And if you want to say "animals", then I'll just have to keep asking the same question until we get to the first life form. And even the scientific community doesn't claim to know how that came into being. What they refuse to admit is their desperation to avoiding creationism is pushing them down a really, really dumb path (e.g. abiogenesis is basically spontaneous generation pushed into a time where no one can ever verify it again), where they create theories right now and teach things in school that have been disproven decades ago, and when people call them out for it, they say things like "You're throwing a tantrum".
I'm the one ranting? I've just started propositions. Whether they're true or not, they were just that, and no more. You're the one who knows so little that you have to attack me to make your responses take up more space. I know far more about science than you'd think, and I didn't even like it in school. I also am not dumb, so you can just quit trying to waste space arguing by insulting me. It doesn't work, nor should it.
