Well the essence of being there kinda proves it. We can't tell what others are thinking, meaning we aren't one collective mind. And if we don't exist in the first place, death wouldn't make sense. We can't just not exist a second time. As to the feeling of being, why would we feel emotions if we don't exist? How do we become depressed? We feel things. I mean it could just be one elaborate simulation (lol) for example the wind on your face on a windy day, it could all be a simulation but if it is it truly feels we are there. I don't think we don't exist, I feel like we truly exist. Idk where I am going with this I'm just kind of compiling my thoughts haha. But this thread has truly got me thinking. Thank you.
