evidence vs. proof

[thedaffodils]

Hi! Could you please tell me the difference between "evidence" and "proof"? I am not clear about it after I looked them up in my dictionary.

I made two sentences by myself as below, and could you tell me which words are appropriate?

1. I have enough evidences/proofs, i.e. statistical figure, to defense my points in my arguement about green house gases are germane to global warming.

2. Police present some evidences/proofs, i.e. witnesses, a bloody knife, against the defendant on the charge of murdering.

Many thanks!


P.S. The definitions are excerpts from the Cambridge Dictionary.

proof (SHOWING TRUTH) /pru:f/ noun [C or U]
a fact or piece of information which shows that something exists or is true:
[+ that] Do they have any proof that it was Hampson who stole the goods?
I have a suspicion that he's having an affair, though I don't have any concrete (= definite) proof.
If anyone needs proof of Andrew Davies' genius as a writer, this novel is it.
"How old are you?" "Twenty-one." "Have you got any proof on you?"
Keep your receipt as proof of purchase.

evidence noun [u]
one or more reasons for believing that something is or is not true:

To have proof you need evidence. If you have enough evidence then you have proof.

For example if the Police were looking for a murderer and they found a man with blood on his hands. That would be one piece of evidence. If they found a knife in his pocket, that would be more evidence.

When they have enough evidence they have proof.
