Sure it is. It's round. Can't get more perfect than that. And our planet has ideal conditions for life. I guess you've never been to Hawaii?
We have a great deal of accidental order: earth rotating on its axis, sun, moon, equal light and day, rain, soil, etc., etc.
The earth is not a perfect sphere.
You forget to mention the earthquakes, volcanic eruptions (which made Haiwaii), tsunamis, hurricanes, blizzards and general natural occurences which are not very conducive to life.
Arthritis, cancer, congenital disease; these are the results of 'intelligent design'?
And of course the appendix, a useless organ that can potentially kill us has been intelligently designed as well?
Yes, life can exist here, but it is not
optimal and one would expect far more from an omipotent, infallible god than this mud mall we are stuck on.
