The one thing that gets me in all this is the Intelligent Design people, people who try to mix religion with science. It just seems wrong to me but I did have a wierd throught on this.
Earth just happens to be in the biozone for life developing around a star, and just happens to be out far enough fromt he galactic core to avoid the harsh radiation there. We just happen to have a moon for us to reach for and it has water (in the form of ice) in one of its poles. We just happen to have two neighboring planets, Venus and Mars, that can be terraformed, an asteroid field with tons of minerals we can use when we get their, multiple gas giants to use as fuel sources, and a moon at one of them that is filled with water that we can use.
It just seems a tad coincidential to me.
