Is rebirth scientifically proven?

I am from a Buddhist family, in which my parents believe in Buddhism a lot (100%). But after learning tech, science, and IT in the last five years, what I feel is the idea of rebirth is nothing more than an ancient Far Eastern religious belief, which is utterly impossible. For rebirth to be real, there would need to be: - The ability for consciousness or awareness to survive the death of the brain of the person concerned. This is an impossibility, since consciousness is an exceedingly complex function of the electrical and biochemical activity inside a living brain, and as far as we’re currently aware, only in the brain of certain higher mammals. The definition of death is when all electrical and biochemical activity in the brain ceases, and consequently everything which was ever held in that brain, vanishes. It doesn’t ‘go’ anywhere, it simply ceases to exist. - The ability for a person’s consciousness or awareness to exist both extra-corporeally and immaterially. There is no mechanism which allows for such a thing even when related to a living brain, let alone a dead one. For this to happen, several of the fundamental laws of science would need to be violated. - The ability for this extra-corporeal consciousness or awareness not only to survive the death of the brain in which it originated, and then continue in existence in an immaterial form for an undefined period, but then to somehow find its way into the brain of another person who might not even be born yet—we’re well into the realm of pure fantasy or science fiction here! So what I want to know is: has rebirth been scientifically proven or is it true?
