Yes it is, the definition of a scientific theory is something that has been proven to be true as far as we know it. We leave room for modification as in Newton's theory of gravity was modified by Einstein, however the fundamental principle did not change.
Before theory we have the hypothesis, which is essentially the guess; once the hypothesis is proved it become theory, which is scientific fact. look it up if you don't believe me.
One might be able to to justify evolution within a species . There is zero evidence of of cross species or the creating of life .
There is a mountain of evidence, it's called fossil record, look it up if you don't believe me.
thanks for taking the time for a dialog .
It seem that we have hit the wall of Religion vs Evolution . I personally have respect for the people who hold views on both sides . I do not think that it is a either or problem . One does not have to prove Religion is wrong for Evolution to be correct , or the opposite . Each one should stand or fall on its own merit . One is scientific and the other is faith based .
Fact and Theory .
This is one that concerns me . If an understanding of this is not understood then the whole conversation falls .
A Fact is a thing that is indisputable the case .
What we believe to be or wish has nothing to do with making something a Fact . We must agree that Evolution is a Theory and not indisputable . To this date Evolution is the best scientific explanation as far as we know it , But it is not absolute or fact at this time .
I made the mistake in being vague in my response to your post . It is a subject that you are compassionate about . A subject that should be discussed in good faith and not avoided .
