No you sixth grade level student, science deals in EVIDENCE, not proof.
This is not about being pedantic, this is about knowing the scientific method and how it works. You start out with an idea that if testable is a scientific hypothesis, this hypothesis makes predictions that are testable and if those tests do not work out the hypothesis is either remodelled or scrapped all together, if it pans out then that is EVIDENCE in favour of the hypothesis.
It's not proof because if something is proved, then you are done, no need to research anymore now that it's proven.
Observations, such as the shape of the earth, confirms the hypothesis but are not proof, they are further evidence of the theory. There are a number of confirmed observations regarded as scientific facts (evolution is one of them, gravity is not) but even that does not amount to proof.
Why? Because the scientific method does not allow for it so you literally cannot have it.
And this concludes my introduction to the scientific process post, you are welcome.
