There is no proof for evolution in the same way that there is no proof for any other scientific fact. The whole point of science is that it shows things BEYOND REASONABLE DOUBT. We lazily use the word proof to describe things that are taken as true because there is so much evidence for it.
Take for example the secondary school chemistry experiment where you heat blue copper sulphate and it turns white. It is impossible for us to prove that it will always turn white because that would mean heating EVERY bit of copper sulphate on the planet. However, because it has turned white on EVERY SINGLE OCCASION we take it as fact because it is BEYOND REASONABLE DOUBT that it is going to turn white.
Take a bigger example. No-one can PROVE that the sun will rise every morning because we only make the assumption based on the fact that is has done so for the past billions of years. However, would ANY SANE PERSON say that the sun rising is only a theory and there’s as much argument for the fact that in fact the sun WON’T RISE tomorrow morning? Of course not, the notion is ridiculous.
THAT is how science works because there is no such thing as absolute proof in science. For that reason there is no proof of evolution and I have never said there was. However, there is an OVERWHELMING amount of evidence that supports the theory of evolution.
There is NO WAY that evolution and creation
have equal standing because there is not even 1% of evidence for creation as there is for evolution. The ONLY ARGUMENT a Creationist has it pointing out how evolution is wrong. EVIDENCE AGAINST EVOLUTION IS NOT EVIDENCE FOR CREATION. The usual 5 questions get asked by creationists as arguments against evolution. These are:
(1)Evolution has never been observed.
(2)Evolution violates the 2nd law of thermodynamics.
(3)There are no transitional fossils.
(4)The theory of evolution says that life originated, and evolution proceeds, by random chance.
(5)Evolution is only a theory; it hasn’t been proved.
Number 5 I have dealt with here and the rest of these arguments are shot down on this website and others

If you wish to believe that evolution and creationism have equal validity then let me propose MY THEORY on the origin of life where a huge blue eagle created the world from some pasta. I have no evidence for it but YOU MUST ACCEPT IT because it is a theory like evolution! Notice how nonsensical this line of arugment is.
The Bible cannot be used to prove itself and there is no other non-religious text that backs up the creation of the world. For that reason, the account cannot be trusted as a reliable historical or literal document. What about the other religions that have different versions of the creation story, do you accept them as valid too? Or do you just go for “7 day Creation vs Evolution” because that is the most popular one?
Individual scientists may not be objective but science IS objective because it does not have hidden agendas and does have a goal that it is setting out to prove. If a rogue scientist does have a chip on his/her shoulder and proclaims something that isn’t scientificially true, then during the rigorous process of testing the claim, he will be found out as a fraud. All major scientific claims, including evolution, have undergone endless amounts of scrutiny but the top scientists of the world. As a result, the scientific world now accepts that natural selection does occur without a doubt and the theory that we came from a common ancestor is considered to be the best model we have at the moment. The Creation story is not even given a second thought because there is not substantial scientific evidence to support it.
