Medicine for example, Isn't it cool how the ingredients to heal a person is here on the earth? There is no way that this happened naturally. And we evolved from monkeys? Really? If we evolved from monkeys or primates why are they still around? Were they unworthy of evolution? And if they were at the time why haven't they evolved into something new today? Also if gravity was a tad bit stronger we'd be too close to the sun to live, and if gravity was a tad less earth would be floating away to no where. There is no way earth could have been put where it is by accident.
