      Time started with the big bang (estimated to be over 13 billion years ago). So we know how long the past is but we don’t know how long the future is. Time could continue on infinitely, even though we might not be around to see it and so the future could be longer than the past.

      It depends what model of the universe you believe in. Some scientists think that the universe will continue to expand forever (in which case the answer to your question is easily the future).
      Other people predict that the universe will stop growing and then will start shrinking until it doesn’t exist any more. The universe is definitely growing at the moment though, so we’re not at the half way point yet so the future must be longer.
      Other people think that we might all get sucked into a massive black hole and the universe will end that way. I have no idea if/when this might happen, so who knows which is longer!
