'The World is Perfect' Argument

If it were not for very many many factors about Earth and the Solar System, we would not exist. I have heard time and time again that this is a valid argument as to why god is real (1st question). However, this logic is very much flawed.

The Earth is situated in the Solar System in what is called the "Goldilocks Zone." If we were very much closer or further from the sun, life could not exist due to the extreme temperatures. We would have either been burnt up like Mercury or frozen like Mars.

The Moon is also a very important aspect as to why life exists. Long ago during the formation of the planets, a planet sized object smashed into the Earth causing excessive debris to fall off the Earth and into orbit. The debris would eventually, because of the affects of gravity in space, clump together and form the moon. If we did not have the moon then we would not have such powerful tides to stir up the minerals and organic molecules in the oceans. Without the moon, life may not have thrived as well as it has.

Jupiter: if it did not exist, we would have been bombarded with thousands of asteroids from the outer rims of the solar system. Jupiter's gravity is so powerful that it acts as a sort of bodyguard for the small inner planets like Earth. Anything that gets in too close is eventually sucked up by Jupiter, thus saving our sorry asses from annihilation.

Anyways...the point is there are many things that contribute to us existing. However, the only thing this PROVES is that we exist and that's what it takes for us to exist. It in no way whatsoever implies the need for a creator. You may say it is coincidence, but I say it's probability. There are trillions of stars, many with a multitude of planets. The probability is actually fairly good that another planet will have all of the same benefits that the Earth does for life survival. If these people looked into astronomy a little better rather than jumping to conclusions, they would understand what they were talking about and maybe not further delude poor questioning minds.
