Well, strictly speaking, you do live in the past; we all do, in the sense that our sense of the present moment is really a memory. Look at your screen now; your visual sensation of the screen is not actually as it is now, it is as it was 0.4 seconds ago. Look at the Moon tonight, your conscious awareness of the Moon is as it was 1.7 seconds ago.
Evolutionary sufficient for us to share an understanding of the term 'Present' and for us all to operate within it whether we choose to be pedantic about it.
This continual degradation of sophisticated capability by people on this thread surely challenges the very scientism you seem to espouse since you reduce the whole universe to what a human faculty, science, can come up with...….and then you demean human faculty.
In other words if, as you say, science is down to human faculty then we aren't. according to you, going to get far with it.
On the other hand if science and human faculty 'taps in to something greater' ( platonism ) then we can celebrate our faculties instead of rubbishing them.
So. What is it to be?
