Why does science always upstage God?

Then there's the 'Fine tuning' thing. Where?
The Earth sits in a zone along with Venus and Mars that we're pretty sure allow for liquid water under an atmosphere. So we're one out of three there.
Then there's the orbit of the Earth which meanders over a few million miles per orbit, hence effecting the temperature for all involved just a little bit.
Followed by the wobble in the Earth's rotation that screws with things just a little bit more.
Then you've got the constant flexing of the Earth by the Moon as it meanders back and forth in its orbit heating the place up and causing tectonic shifts, earthquakes, volcanoes.....
The list of things 'Out of whack' in the system just goes on and on and on..... Would you like to know more?

The "Fine tuning" argument is around the range of possible physical constants, and the proposal that most of that potential parameter space could not lead to any sort of life (not just life as we know it).  If there is no physical "reason" for the current values of physical constants, then they must have been chosen by a god.

It is a good question.  Possible answers are that what appear to be "free parameters" in physics are not free at all, or that there is a multiverse where different physics applies in different regions or versions (and only habitable universes will have creatures asking these questions).

Of course, if it were a god designing the universe, why is it so hostile to life?  We might be the only intelligent civilization in our galaxy at present.  It certainly doesn't seem designed for life.
