First of all, by definition the "Theory of Evolution" has not in fact been proven. (If it had, it would not be called a theory.)
This is an unfortunate all too common error.
1. Nothing has been "proven". That is not science.
2. You are corrupting the term 'theory' to mean something it does not.
Quick challenge
Please list the following in order of scientific importance:
Hypotheses, facts, laws, theories
Unfortunately I am going to have to provide the correct answer in order to continue this post but kindly try to answer it as you would before consulting the answer, (if you haven't seen it already).
It's of no surprise to see that laypeople generally get it wrong. This is due to it being a seriously common misunderstanding.
Answer
Theories
Laws
Hypotheses
Facts
Most people tend to put 'facts' first - taking 'fact' to mean 'proven'. This of course is not true and it need be noted here, in bold, that theories do not become facts, they explain facts.
Facts are observations that are not themselves tested due to numerous observation. For instance, should you hold an object in your hand and let go, it will fall to the floor. This is a fact - but facts are not necessarily true. Should you be holding that object in space, it wouldn't fall to the floor, likewise if you were on a lift with broken cables, plummeting to the ground at 9.8 metres/second2.
A 'theory' "incorporates facts, laws, inferences and hypotheses" (National Academy of Sciences 1998: 7).
A theory is an explanation of those observations. It is not a guess, hunch or 'proven', (all science is tentative).
“The formal scientific definition of theory is quite different from the everyday meaning of the word. It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence.” (National Academy of Sciences 2008: 11)
Please, take some time to become familiar with the terms science uses and how it uses them. And finally, kindly drop statements like "it's not proven" - nothing is, the statement has no value.
