I have been trying to conduct a proper statistically valid survey amongst dead people, but the response rate is too low to form any conclusive opinions.....
that's a bit like asking if there's any concrete evidence of the year 2015. There isn't, but nobody doubts that there will be one - do you? In fact cazzz has provided a link to some evidence but presumably it's not concrete enough for you, perhaps because your mind is already made up.
Not at all sure how you can equate the two questions.
Everyone believes there will be a future for time - but will there be one for us?
You also make assumtions with no grounding.
It is obviously you who have your mind made up if you don't mind.
