Modern science cannot have one thing to say about the possibility of an afterlife.
On the contrary, it can. Based on what science has found out about nature in general, and about brains and minds in particular, it can say of the afterlife that it is rather unlikely. Science could be wrong on that account, but as long as each and every investigation into the matter, under controlled circumstances, yields zero results, I think we can safely assume that the afterlife is most probably a myth.
('Safely', 'assume', and 'most probably', that's three terms of tentativity in one sentence. A bit overdone?)
