Life after death?

I do not believe in life after death.
There is no heaven and there is no hell either.
Heaven and hell are situated in the realm of your nlind faith which is nothing but a superstitious idea.
What we cannot see in our naked eyes is absolutely non-existent. But if you say that we cannot see air in our naked eyes but we know for sure that air exists. Yes, air exists. We can feel it, we can sense it.
But we cannot feel or sense the existence of heaven or hell.
After death, neither we get a new shelter in heaven nor we burn in the catastrophe of hell.
After death, we are simply reduced to dust of nature.
We are born out of nature and we die into nature. So to speak, we come from nature and go back to the nature in the end.
Our birth and death are a natural process. But it is not natural that we would be reborn some day after our death.
Life after death is next to impossible. If it so happens, then all our scientific knowledge would be reduced to nothingness.
