How can anybody be so dumb as to think we descended from monkeys? Was your grandfather a monkey? Mine neither.
Nevertheless, there is real evidence. This video explains just a little of it, and there’s plenty more. In fact, there is such an overwhelming amount of evidence that only people ignorant of it are likely to doubt the fact of evolution. And remember, we’re all ignorant. Just on different subjects. (I think Mark Twain said that, and it’s true.)
Don’t choose to be ignorant about evolution. It matters what you believe.
