Why can't God make more women from men's ribs, and men from dust?

@jumb0mumb0 I though we we're debating that facts, not my grammar. I'm a science student, not an English one. It's amusing that instead of trying to debate the facts (which you clearly can't do) you critisice my grammar. I only tend to worry about my grammar and spelling when i'm writing up lab reports, not on youtube....

@Erech01

In the process of criticizing another person for being wrong, you yourself were erroneous, fucking dip shit!! It's the contraction "you're" that you were searching for in your primitive mind but could not find.

Stop arguing with creationists, it will get you no where. Your sentence structure and grammar are hideous, you MUST stay in school if you ever want to become more than a waste of space!!! Haha

Satan made the humming birds...all hail the almighty.

I want to know how evolution really works. This video is just a repeat of the random variation and natural selection theme that is only an outline of what evolution must accomplish.

1. Where and when in the reproductive cycle does the random variation occur?

2. How is the body plan modified and where does it reside?

2a. Proteins have to be organinzed into tissues.

2b. Tissues have to be organized into organs.

2c. Organs have to be organized into body plans.

i just looked here to see the comments. and i wasn't wrong: the video is mostly commented by complete idiots, who are trying to convince each other that their point of view is the right one. new scientific discoveries are constantly made, the truth changes over time, so why should we let it influence our lives? seriously people, don't you have anything better to do than discuss evolution on youtube of all places? now I'll navigate to another video discussing evolution and see if it's the same
