When my body dies, I still exist. Not as this particular self, with a particular id, a particular history of experiences, etc... but I still exist. Because I believe we are no more or less than cells. That are constantly "borning" and "dying". We are One Self.
There's no one special. There are only "program errors". And the result is Einsteins, Jimmy Hendrixs, Van goghs.. Or deficient persons with mental or body disabilities.
We are organic life. And organic life, for me, is a very complex "program" that rebuilds it self, corrects errors to itself by itself ( just like our bodys. You don't need to think, or be aware, of the process of curing your head hackes or your constipations. The body corrects those errors by itself ). And the only way to make it grow (evolution), is to pick monkeys (in this case) and give them freewill, the believe of their Uniqueness, conscious of pleasure, counscious of feelings etc... This leads to where we are now. Everyone(almost) thinks they are special. They are not. We are not. We are the same.
"I am you and what I see is me"
In our daylife, we are constantly seeing other beings. But actually they are no they. They are you. The thing is, as Alan Watts said, "we can only be on one place each time". We are One.
Try to put it this way, you think ents are special in their nests? Like ents are all diferent from each other, they are unique and separate from all other ents? No. They are a complex organism. A complex form of energy(life). Just like we are, or bees, or roses, or mosquitos, or sharks, or mushrooms, or whatever.... We are complex organisms , living inside a complex organism, that lives inside another complex organism, and another and another... and we call it Universe. And... we are made of complex organisms, that are made of complex organisms, that are made of...that I call it Universe also.
There is no end and there is no start. There is only Self Existance. (ent is a self, you are a self, a plant is a self)
Yet, I believe we, as Human race, are more complex than ents or any other form of life living on this planet. I don't need to justify it. Just look around.
So.. if I die, I believe, I'm still here. I am you. Or anyother thing living on this planet.
We are made of energy. And organic life is made of energy. And the Self that "controls" the distribution of energy in this planet will pick my or your or who/whatever energy "dies" and sends it another way. Or simply vanishs, to "born" another form of life/energy.
And we as a race, can't handle this extra energy that was given to us. Because we are apes with superpowers. And we can't handle it. That's why we live with all this wars, hunger, thirst, muderings (not only between us, but also against other forms of life), defilers, pedophilia, mental disorders, suicide, and the list goes on and on...
The enviornment that we created to live in is starting (well, already started long time ago) to get too much complex. We can't handle it.
So what is coming, in my opinion, or it's a evolutionary step in our conscioussness. So we can handle the enviornment that we've been creating since.. I don't know...decades(?). Or there will be Khaos and Auto-Self-Destruction. And for me, this last option makes more sense than the first one(since it's only a hope). Because if I continue with my speech of all this are complex organisms that are made of more complex organisms, and so on... So, for me, it suits perfectly the Idea that the Life of the Earth has come to an end. Like the Earth "soul"/energy will vanish to another place in the universe, where it's needed.
For me, every planet on our solar system, had Life once. But it had to come to an end. Just like everything. And what it's left, it's the Planet (mars for example). Just like ourselfs or anyother life form. When we die, we leave our body behind and the energy is sended another way, where it's needed.
I hope I made my opinion clear of what all this "shit" is.

And sorry if the english is not that good.
Love
