In science, when testing the existence of something, the burden of proof is generally on the one hypothesizing the existence. The existence is generally accepted if experiments fail to reject the hypothesis.
But free will is a concept, a way of viewing the world. It’s not a physical object or mechanical process that can be tested. It’s why trying to prove it scientifically or through logic is just as impossible as trying to disprove it.
It’s a philosophical debate, not a science experiment. In philosophy, a declarative statement asserting the affirmative is always true is just as big a fallacy as saying the negative is always true.
