This depends on what you mean by 'prove'. Science cannot technically prove
anything, and accepts provisionality as one of its guiding principles.
What I call 'true' free will would necessitate some sort of independent homunculus whose volition determines the courses of action that I take.
The existence of such a homunculus is untestable, and therefore nothing that the natural sciences would concern themselves with.
You could argue that the existence of such a homunculus is unnecessary, as consciousness and volition can be shown to originate from purely physical electrochemical processes in the brain.
While this is not actually the case
yet, I do find it likely that advancements in neuroscience will eventually give us an effectively complete understanding of the brain, and consequently, consciousness/will. Environmental factors (especially physical trauma) have been shown to significantly alter cognition and behavior, lending credence to the 'purely physical' hypothesis.
Even so, superfluousness does not necessarily equal nonexistence, and perhaps free will is an 'emergent' phenomenon, with an external homunculus 'tethering' itself to a 'like-minded' body, brain lesions would inhibit this 'connection', resulting in altered behavior.
Though, if the homunculus
does exist, would that
really confer free will. How would the homunculus make decisions? We would be free of natural interference with free will, but at some point we would have had to develop a personality, which requires experiencing external stimulus, which is ultimately beyond our control.

Assuming
you hold some sort of naturalistic worldview, neither do
you. Indeed, regardless of your worldview, you'll find that there are only a handful of things that we can 'truly' know,
You might find a short reading on the Münchhausen Trilemma a bit interesting

Granger wrote:With science one starts with a belief (hypothesis) and then comes the hard part of checking all the facts and in case reality is different to discard the idea and start again.
With religion one just believes in something (without even checking facts) and in case science (or reality) comes and proves it wrong one just adds another layer of unproven falsehood around the disproved one in a futile attempt to shield it from the harsh reality.
Bottom line: the difference is in the ability to adapt to reality, which seems to be lacking in case you're infected with religion.
You seem to have a fairly narrow concept of religion.
While many religions do incorporate a well-defined set of 'unchanging' core beliefs (stymieing adaptation), and then declare heterodox practitioners heretics, this is by no means universal.
Suppose someone chose to adhere to religious doctrine with the understanding that beliefs do not amount to knowledge, freely adapting these beliefs as they are made privy to new information (many fundamentalists do this as well, while maintaining the 'same' position, but refuse to admit it).
Granger wrote:and proves it wrong
There are myriad religious beliefs that science has not, and will not ever, 'prove' wrong, simply because they are untestable hypotheses, confined to the realm of metaphysics.
Ultimately, your position is dependent on external stimulus and the foundational axioms through which you filter that stimulus to arrive at conclusions, idols carved from the same arbitrary granite as those you deride.
With regards to the topic:
I suppose free will may or may not exist, I could lean one way or the other depending on how it is defined.
