Life after the death:Hell or heaven?

On the other day, amid work hours I got into an argument with one of my colleagues (Imagine,It didnt scathe the work.).The subject was 'The existence of life after death'.

He being a dedicated devotee, argued with his full potential for the existence of such a popular concept.He quoted religious books to support his stance.

According to him and a vast majority of the world population, the Hell is a place that might look like this.

If your way of life is one that completely challenges the moralities prescribed by the religion you believe in,I bet you will end up in the great hell.There this mountain-sized fire awaits you to fully devour and,interestingly,you have to spend your infinitely allocated time here forever!There is no escape from it and no death indeed!

To those who live a morale life according to what their religion says,there comes a good news!You will directly be sent to the heaven right after your death.There will only be a delay of 2.4 hours because The God has to allocate your seats according to the size of your righteousness(Mr.God has sued bid bots for copying his Modus operandi!).You can rejoice because this is how the heaven probably look like-

Last word : I don't believe in such things.I have only one question to shoot at those who heavily stand for and propagate this kind of myths:

What is the need to think about and prepare for a life that may happen only after your death rather than living in the presence?

Your takes are very much welcome.Because healthy arguments are good for both parties involved!
