You are asking what we think and about hope. Both of these are about beliefs and not based on real evidence. There are tons of Belief Systems (B.S.) out there to choose from but they are all based on assumptions (I.e. the Bible is inerrentand God's word)
Some of these things are provably wrong, for example we can prove whether or not the bible is inerrent by simply reading it. That doesn't mean that there's no god or that your faith in him or in JC won't save you but that would all be blind faith since there's no evidence to suggest its true.
Each of us have our own experience, if I told you that I saw Jesus in a potato chip and he healed my broken leg, would it convince you? Likely you be convinced that I'm lying or crazy, and rightly so.
In my opinion, you have to experience the truth for yourself, otherwise its simply more B.S. And you adopt someone else's ideas. I like Thomas Campbell's "my big toe", his big Theory Of Everything which he has outlined in detail in his YouTube videos as well as his book. A quick search for the name on YouTube gets to his channel. I won't outline it here but it's backed by way more science (even physics) than religions around the world and even explains many of their teachings without the dogma usually attached. I like it, it's seems to fit with my own observations thus far but I don't BELEVE it all, until I can experience some of the deeper consequences of the theory, I would consider it simply the best theory there is. If I can replicate his findings, I can prove it to myself, at which point there is no longer believing any of it, it is simply KNOWING.
According to the TOE, which is more suited to answer this question of yours than the other stuff out there (imho), the answer is yes there is life after death but life as well as death are not what we have believed it to be. A bit similar to the ideas of reincarnation but much more open-ended. Much of it is provable with science but some of it is really only provable on the individual level, no one can prove it for you.
