Death might be a very complex topic to talk about. Most, don't even want to talk about it because that would remind them of their mortality.

We have come up with so many theories of what happens after we die. Heaven, Hell, reincarnation or eternal nothingness.

Religion is meant to deeply engrave a codex and to live by it. But the other reason is to take away the fear of death.
Atheists believe only in one lifetime, that nothing will happen after they die.

Is any of them true?

We always seek for impossible answers, enlightenment, wisdom. We stick to a belief, we philosophize about the unknown.

Are we alone, what is the meaning of life, who are we?
I already talked about the meaning of life and now I will explain my own theory about death.
And since it is a scientific approach, we will talk about evolution and instincts.

First off, what are instincts?

Instincts are preprogrammed reactions to specific situations, fight or flight or the mother instincts are few examples.
But how do we know them, why do we have these programmes?
That can be explained with evolution. A species have come across many dangers in their history, those mechanisms saved our lives many times. But we had to learn them, encounter those problems multiple times. It is like a form of conditioning, with the right variable (reward and punishment) you could programme a reaction in a person or animal
.

You can teach a mouse to respond to stimulation and activate a lever.
That is just a simple explanation to conditioning, but let's go back to instincts.
Instincts are saved in our DNA, that is why babies unconsciously know to hold their breath underwater.
Experiences will be inherited by former generations.

DNA

The DNA are building bricks of your body and mind, it is possible to pass on certain traits to your child. Positive and negative ones. Positive ones would be talents or cognitive capabilities.
Negative ones are physical or mental illnesses.
I may sound cryptic now, but what I am trying to say is, that information can be passed on to your descendants.

A part of you and your experiences will be shared with your child.

Like I said, that is only my own theory.
I am not a scientist, nor am I quite religious. I only wanted to share my thoughts on this matter with you.

What do you think will happen after we die?
