This is one of the most debated topics in science and religion.  And the comments on this thread are very inquisitive.

Commenter “JB” had this to say:

Time is a HUMAN CONSTRUCT .  Outside of human understanding —- IT DOES NOT EXIST . It is a template which humans have made & applied  to help us understand the ‘ human condition ‘.  i.e. That we live on a tiny planet within the solar system & move around a large star called the Sun. Time is a template applied to movement so that we can easily understand  how ‘ THINGS CHANGE ‘ –  How THINGS CHANGE is what we call time. Time of itself –  does NOT exist – MOVEMENT & CHANGE exist  –  TIME IS A MAN MADE CONCEPT.  IT DOES NOT EXIST OF ITSELF IN NATURE.

Commenter “trailguy” also had an interesting point of view:

Not sure he addressed the topic. Why not doubt the big bang at least to the extent that it is still banging (and increasing at that). All the space that is being created everywhere is our experience of time. Time should be gradually ticking faster. The arrow of time has to do with the nature of the creation of space. Perhaps with each plank unit of space that is created we experience one plank unit of time. I’m sure I could fill a lecture with such a theory and not get so far off topic
