Thanked: 150IIRC, supernovae have a certain frequency that denotes their explosion, the redshift is how that inital frequency has been altered by the two bodies in question (us and the supernovae) having accelerated away from one another.
We've discussed the difference between evolution happening randomly and happening naturally many times before, there is a huge difference.
Random implies that you have genes that are just mutating and expressing themselves with no regularity, this does not happen in real life. Natural means that the environment that an organism resides in has an affect on how those genes are expressed and that the environmental conditions determine which memberrs of a population pass on the genes that allowed them to survive.
Randomness couldn't be farther from what causes evolution.
First off, you've just barred creationism from the discussion with that first sentence. It's a hard reality to grasp but you've done so quite well. (but seriously, you are correct in that statement and it does eliminate the Supernatural as being credited for natural events).
Secondly, yes science is entirely based on theory, every science book in the world is filled with similar theories. And until they are disproven they will be taught as the prevailing explanation for the phenomena that we observe.
There is no difference between a scientific answer and a scientific theory as you suggest that there is. The reality is that your using a general speech form of the word "theory", not the scientific definition, which is much more rigorous.
I accept.
