^^^Actually we do still exist after death. Nothing ever really dies, only breaks up and becomes something else. You are made up of cells that were once part of other living things, we eat dead things to stay alive.
The creation of our existence isn't a creation because everything we are made up of was once something else. You are made up of other living things, other human's cells and DNA, the plants and meat that you eat. And when you die, you will still exist, you will become many other things. When you you die it's not like you just disappear, no, you will become part of many other things and still exist.
Our bodies are static, in a sense we die everyday, from cutting hair, to sweating, to shedding off skin cells. But these things still exist, everything you are made up of will ALWAYS exist, it will be passed on to be other things.
From reproducing and passing your cells onto other humans to dying and being consumed by other living things(bacteria, maggots, plants). It's a cycle... nothing ceases to exist...nothing is created.
This is what science tells us, nothing ever really ceases to exist, only becomes something else. In a sense we are all immortal.
