The question is how the questioner exists.

So far we have done too much of 'spatial engineering'. The real thing is 'non-spatial engineering'.

The angel within me thrives on the devil within me.

Philosophy is the only excuse God has for his cruelty and vanity.

The discovery of God begins at understanding that He ought to exist, and ends at knowing how He could exist.

If the universe is a non-spatial computer, a 'time machine' is a program that allows a user to have the same (ontologically non-spatial) feelings or experiences that occurred or s/he merely feels to have occurred in the past, with an in-built function to have different feelings or experiences than those of the past, and thus creating a possibility to change the past or to rewrite history in a pseudo sense.
