I wouldn't say death is part of the point in life but it is a realisation of why we are here and that this world isn't going to last forever so there's no point accumulating everything for this world as it will all perish one day.
The point of this life is to worship the One true God according to Islam. If we worship Him, we please Him and if we please Him, the ultimate reward is entrance into Paradise which is forever. There is no illness there, no malice there, no tiredness there and we meet God there.
I think I was afraid of death but when I had my children I've taught them not to be afraid of death. I explain it to them in a way that understand that this life isn't forever, some people go to God young, some when old, some middle aged. It doesn't matter when as we all go eventually but it's about what we did in this life and Islam teaches us to worship Allah and be good and not to hurt anyone. If we ever make mistakes we quickly ask for forgiveness. That way death will never scare them whereas I have made many mistakes in my life which I wish I could change but I need to make up for it before I leave this world. An example may be debt or missed prayers (we pray 5 times a day, we always have something to do in Islam).
The easiest way to find how God wants us to live in this life is to first look at the Qur'an and find a teacher to study by. This keeps the chain of knowledge going and goes all the way back to the final Messenger peace be upon him.
The thing is, people may be afraid of death because of leaving family behind etc. but I've read accounts of children who placed their trust in God for food and shelter (in past times). I teach my children to be we be afraid of what could happen but use that thought to pray to God instead to look after them, and if they have children when they are older then for God to look after their children because at the end of the day, shelter, sustenance, health etc. come from God, not any human. It only happens by His will.
I hope this helps them. If this was written as a story and read to me as a child, I think I would have understood life better through my teens but I guess it's a learning curve for me.
