Agree.
Actually, I was referring to the laws of nature (I.e., gravity) and how they work so well we can set our watches by them.
All shielded from the earth by our core giving us the magnetic field. If it weren't for that, a lot more than our "electronic devices" would be fried..
We are a product of the laws of nature. The 24 hour day didn't exist prior to earth, rather because of the conditions that happen to exist on earth were measured and humans divided one rotation of the planet into 24 increments that individually we know as an hour.
It is the same has how water doesn't magically happen to boil at the nice round even number of 100C. No, the scale was built around the properties of water.
If we didn't have a magnetic field, we might end up like Mars with a thin atmosphere that has been eroded for many years of solar wind with no magnetic field to protect it. Earth is bigger and has more gravity than Mars, so maybe that would take longer, if there is life maybe it could and would adapt, maybe life would die out. Who knows. But I don't think that shows that earth was created for us more than it shows how we have evolved is simply a consequence of our planet's properties.
Humans really haven't been here very long at all when looking at our amount of time in existence compared to time scales used when talking about the universe. Think of all the limitations we have, all the things we can't do, how fragile we really are, all the ways the universe can kill us at any time. That has happened in the past, natural events that have wiped out entire species and completely changed the course of life's evolution. We've only survived for the blink of an eye so far, that can change instantly. I just don't see our planet or the universe as something intelligently designed for us.
I see us as a consequence of the natural processes of the universe, maybe just an evolutionary step in the universe's progression. I know the analogy is old, but I think it is very accurate. Being that a puddle that fits just right in a hole in the ground could consider to itself (if it alive and conscious) how the hole is just right for it, how the nooks and crannies hold just enough water to let the puddle fill the hole just right. *edit - The hole didn't get created to support that specific puddle, the puddle just happened to form there and is how it is due to the conditions that were present when the puddle formed. I know it is overly simplistic, but I think there are plenty of parallels.
