And, let us add here life as we know it... which is of course limited to what you find on rocky planets with liquid water.
Right...I'll just keep it to that. No need to define life in anyother way in this paticular thread.
So currently, in order to support life, a planet must:
Be in a system in the Galactic Habitable Zone.
Be in a single-star system containing a main sequence star.
Orbit the main sequence star in the star's Habitable Zone (or receive sufficient radiation from nearby bodies to maintain HZ-like conditions).
Be rocky.
Contain liquid water.
Thanks for the in depth response. That just proves how rare and the nearly impossible odds that planet earth has landed itself in. It helps me in my own little world justify the design of us and our planet as a creation with all the right parts in place.
My personal argument hasn't changed one bit. I still challenge any creationist to show me a single piece of evidence to refute the theory of common descent.... anyone? Not once in this thread has anybody even tried to do that.
I didn't mean you personally are a flip flopper. In your life time the general rules may not change. Over the past few hundred years for the next few hundred years is my gage for the changing argument.
We have gone over the common descent before. It was in the context of god wouldn't reinvent the wheel to make a different species. Even if the doesn't stick with anyone, I DID at least try to comment on that.
You seem to be slightly misrepresenting what science is about. As new evidence comes to light, theories change, textbooks are updated etc., but you have to make a distinction between established facts and points of contention. The fact of the matter is that no evidence that has been put forth to refute the theory of common descent has survived scrutiny. In my book, that makes it established fact, not a so-called 'controversial theory'. It is extremely unlikely that it will be proved to be incorrect, and as such it is extremely unlikely that you will find scientists changing their minds or their arguments about it.
Until you CAN prove the origin of the universe, many of the FACTS that you state are subject argument. It is this point that gives me every right to look at scientific theory with a skeptical eye.
