Human aren't immortal, however we still do not understand the limit of our lifespan. The only reason why we die are due to reason such as aging cells that are unable to fight and heal as they once '''did and it has been speculatated that we are unable to die of old age as the reason that cause our death are most commonly from thing such as injury or disease. Therefore if were to be able to stop the aging of our cell or have cell that can containously regenerate our body, we could be technically consider immortal, however the main cause of our death are generated from disease such as cancer,Hepatitis B. malaria and etc. Also a possibility that explain the fact that there are no time traveller "visiting" us is the fact that we have to build a time machine first before we can time travel, so if you were to visualize two toy car that are moving at the same rate, one of it is "our" timeline and the other is the other timeline that is in the butterfly effect, even though we are in a different timeline we are still progressing and both began at the same time so that would mean that we are progressing in the "main" timeline which mean we have to make a time machine first or wait for the other timeline to produce a time machine and even if they were to time travel we woudnt be able to relize the fact that they are timetravelling since they are traveling in the past and we are in our own timeline at the same time as theris so even if they or (future) we go back in the past we woudd't even know about it. Since going back in time mean going to another timeline. So think of it this way you are in a race track a car finished the race boom you time travel back you would be in another timeline because in your main timeline the race is already over. Also you said '''as soon as time transcends forward the PAST is Eliminated out of existence.That is theortaically impossible as imfomation are always beign stored. For example you looking at the sun is basically you looking at it's past. You looking at thing that have even the slightest of distance are basically you looking at it in it's past therefore infomation of the past will not be eliminate.
