You are conscious so consciousness is possible. Given infinite time, all possibilities have a 99.99..% (repeating) chance of happening. As a result, when you die, it's "almost certain", in the mathematically meaning of the phrase, that you will be conscious again.
Fun Fact: It is incredibly unlikely for life to evolve up to human-like beings, especially considering the universe is only around 14 billion years old. This very strongly suggests that there were many universes capable of supporting life way before ours would reach that stage. So, that allows us to extrapolate that when this universe is no more, another one will replace it, and when that one is done, ....well, I think you get the picture by now, lol.
