Well, you've done it. I have to bring you back to reality now. First of all, your little "humans are bad, mm'kay" speech isn't really evidence for christianity, or anything. The reason it happens is because humans are imperfect creatures that you try to fit into your perfect happy little world view where god watches over us. Humans get sick, they get mental disease - some don't even develop properly; physically or mentally. Sociopathic behavior and stupidity are not evidence for christianity. It is however, evidence that you have no argument.
But let's move beyond such small-minded notions. Let's move beyond this planet. Do you have any idea how massive the universe is? Massive isn't even the right word. Massive is too small of a word. Hell, massive is too small of a word for our solar system. The Earth is "massive".
Here's some perspective. When viewed from beyond the orbit of Pluto(roughly 3.7 billion miles away), the Earth is a pale blue dot suspended in a sun beam. But let's get closer to that. Let's try Mars. When Mars is as it's furthest from Earth, the distance between them is 250 million miles. At their closest, 36 million miles. Now, without going into details about how or why this works, the trip by rocket would take 260 days, ± 10 days. Do you know what that would do to the human body? First of all, if there was an accident and you were exposed to hard vacuum, the following would happen. All of the gases in your body (primarily oxygen) would be ripped out from you; an experience I'm told feels like one's "blood is boiling". After about 10 seconds, the deoxygenated blood would hit your brain and make you black out. Assuming you were left in that state, death would follow quickly within 2 minutes.
Assuming no accident as such happened, and you were able to remain in space; you still would not have a pleasant journey. Muscle begins to atrophy all over your body, because you don't use them anymore. 1.5% bone loss occurs every month from lack of mechanical stress on bones. As a result of that bone loss, the extra calcium in your blood causes potential kidney stones and calcification of soft tissue. That's not the only unpleasant, severely-crippling effect; no - I haven't mentioned the radiation exposure yet. Unprotected by the earth's atmosphere, you receive 10x the normal dose of radiation. This could develop into immunodeficiency, or "god" knows what! Nobody is entirely sure of the long-term effects of exposure to cosmic rays from the sun, and the rest of the galaxy - you see, there's no medium in space to slow down radiation particles. So by the time these astronauts have made it to Mars, they're probably dead anyway. Forgot to mention the 1.6 years they would have to wait for the Earth and Mars to re-align before they could make another 260 day trip back. 🙂
Given that perspective, the solar system is a lonely, cold and dangerous place. What about our next door neighbor, the star Proxima Centauri? Proxima Centauri is relatively close; approximately 4.2 light years away. (Keep in mind that light travels 186,000 miles per second / 300,000 kilometers per second.) Meaning; at light speed, it would take 4.2 years of space travel to get there. Let's say we managed to propel the astronauts to Jupiter, and had them use it as a gravitational slingshot (yes, that maneuver is real, we've done it with the Galileo probe; at 106,000 MPH) in upwards of 150,000 MPH. Long story short; you're looking at a trip that's about 18,000 years, ± 100. Better start packing now, chief! 🙂
Of course, that's nothing compared to the vast 100,000 light year-long galaxy we live in. The nearest spiral galaxy to our own is the great Andromeda galaxy, about 2,500,000 light years away. That's peanuts however; as the edge of the observable universe is about 47,000,000,000 light years away.
So, when the galaxy you live in is a speck from the scope of the unfathomably large and dangerous universe; where do you fit a small-minded and personal god who cares for our well being - into the equation? The notion of such a thing makes me laugh.
TL;DR version: There is no evidence of god. There is however, evidence that we live in a universe governed by physical laws that we can study. 🙂
