We are not able to determine on the basis of the evidence available, whether people actually cease to be aware, whether mind is still active, whether mind is a function of our physiology or independent of it.

I wouldn't say this is really the case. We are constantly seeing evidence of how consciousness is limited and affected by the physiological. That's why simple substance like drugs and alcohol can have a very strong effect on our moods and about minds. Another great examples are physical injuries to the brain that show significant changes in personality and in the case of lobotomies, pretty much full destruction of personality. So it's absolutely unfair to put the two option on equal footing because one is in fact supported by evidence while the other one has very little going for it and is mainly a cultural think connected to indoctrination and so on.

On top of this, we can see and examine the physical processes that lead to consciousness and while there is a lot to learn on that front, the knowledge is constantly expanding. And while doing so, the idea of immortal consciousness seems less and less likely. In fact, there is no mechanism suggested that would allow it, so it might actually be not only unlikely, but impossible.

I would say that most of the assertions in your post about consciousness and spirit are basically wishful thinking in the face of the horrifying idea that our consciousnesses stop existing when are bodies stop functioning. Unfortunately, it's quite likely that this is actually the case.
