If you are religious, stop cherry-picking science

Well, maybe one day they will focus on science enough to be sceptical about their religions.

Thank you for answering.

I was a believer, but now I'm an atheist. But it doesn't mean that I object believers in their faith. Even understanding the science functioning, I'd say that inside science is not everything fine; I mean that science bases on methods, and the methods are as strong and solid as religious dogmas. So, in this interpretations we can say that there's 'fair 50/50'. 
I'm worrying of people, because I don't care of subjects of their believing, but I do care of ways of reaching the point.

So, what is the point I'm talking? I'd say that there's no difference of our imagination if the last point of humanity will be just death and pain.

Imagine two possible situations:

A. that all the people stupidly die in future (at the end of humanity/the World), and all of their history, traditions, inventions, feelings, arts, buildings, money, food, places... all of the things will become to nothing. 
B. that the one last standing family has left alone in the Earth. And the couple is the last hope of all humanity, because they the ones which can spread the history further. 

In case A - everything is nonsense. We can killing each other without any doubt, without any bad felling about it. In case B - there's a hope. I ascribed the situations like this, because I wanted to be as much as neutral to religions/science. So, it's important to me finding the answer solving the task.

I wish you luck!
 

Thank you, V for corrections. I described the situation briefly and in common manner.

The latter situation was being discussioned in seminars of philosophy, so I just even tired to write it, so I thought you'd excuse me of it.
Surely, we can change this 'mind experiment' to more suitable form, f.e. to two pairs of humans, etc. But the main point is neither in the number of people, nor in their health status. 

I reascribe it in another manner, more suitable for any 'current' person:

Let's imagine, that scientists have discovered that the sense of life is in the last n minutes of life (n = 5...15... it can be any number). We don't know how have they found the answer, but the info is 100% true. So, all my life is to live that n minutes of mine. I have plenty of variants: A. I can go this info to hell, and to continue living as I've lived; B. I can do something. C. Some other variants.
What if I choose 'B'?  What should I do? How my life would change?

Egyptians, f.e., were using 'The Book of Dead' for their lives. They say that the book has been more important for them, because the dead life has been valuated more than alive one. So, to know by heart all the magical words/spells is to the key 'to the future'. Egyptians' faith can be helpful in this mind experiment as the more real example.

I am a religious reactionary who strongly supports both science and evolution. It is liberal atheists who are in complete denial. Evolution shows that liberalism leads to idiocracy. Positive human evolution is only possible in a religious society.
