You do have to bring it to that, which was my point. The ego is a collection of thoughts and emotions we self-identify with as ours, and hence "me". Prior to the development of the ego, we identified as our bodies in early childhood. Yet, as we continue to develop, we likewise recognize that like we have a body but are not our body, we have an ego, but are not our ego. Now you are into consciousness itself, as you pointed out. But without trying to go down that path to understand what consciousness actually is, I think it's fair enough to say that all of what goes into this sack of skin we inhabit, whether that's our cells and molecules, our ego constructions, or awareness itself before and beyond all that, the the whole thing is energy collected into this form we call a human, or a cat, or a dog, or a tree, or any other lifeform.
When that lifeform dissolves, where does that energy that coalesced into that go, or in fact came from? And then the question is, what is that energy that took shape over 14.5 billion years of evolution into this "me" I walk around with goes? I'd say it's safe to say, that in fact continues, as it came to form "me" in the first place. But not the form itself. The egoic "me" dissolves just as the body does. But the energy that became does not, but is rather transmuted and continues to take form, just as it has from the beginning and continues to do until the universe itself dies. And then it goes.....?
But to answer the question about supposed "life after death", I'd say in most cases that is an egoic projection, an immortality project that can't let go of self-identification as the form we currently identify with. I don't believe in some pure nihilism, but I also don't believe this "Me" who I am will go skipping along after this body turns to dust. I am afterall, 14.5 billion years of evolution walking on two legs. You don't think that process is going to continue after this form dies?
