The Earth, God, scientific theory...Earth is too perfect?

My mother has always said how can the earth be so perfect without the hand of God? The perfect distance from the sun, a few million in and we would fry a few million out we would freeze. The gravity and the atmosphere are ideal for life. I say that is exactly WHY there is life...because this planet evolved in such a perfect condition and life developed BECAUSE it was perfect. Life certainly isn't as common as Star Trek implies, and a Class "M" (Earth-like) planet is probably extremely rare. Maybe we are "it" (that would be a bummer), because this planet was such an astronomically odd occurance. Maybe life was accidental, and out of 12 billion light years of expanding space...Earth is unique. What do you think?

Why do people put pills in their mouths before water?

I seen this all the time on television. Personally, I always put water first so I don't have to taste the pills before I take the water.
Is there any reason why pills before water would be better? I doubt the water dissolving the pills is the reason.
