There is actually a very basic explanation. While we, existing in the present, do go from past events to future ones, these events go the other way. First they are in the future and then in the past.
The question is whether time is a fundamental dimension along which the present moves/exists, or is it that motion is constantly rearranging the situation, so that the configuration of the pattern of what exists is continually changing and time is simply a consequence of this motion, as each arrangement is relaced by the next?
Does the earth travel the fourth dimension from yesterday to tomorrow? Or does tomorrow become yesterday because the earth rotates?If you can appreciate that it is the latter, it does explain the many anomalies of time with which physics must contend, such as why it is affected by gravity and velocity. These affect the rate of atomic activity and thus the ticking of the clock determined by that activity. Time as the probabilities of the future collapsing in the activity of the present, then into the determined order of past events, describes a dynamic process, while time as a dimension going from the determination of the past into the vagaries of the future leads to the many worlds scenario, which proposes all possible paths be taken.
Simply, time is a consequence of motion, not the basis for it. This means it actually has more in common with temperature, the scalar average of motion, than space. In fact, I suspect this means space isn’t relativistic, but is an inertial frame that does determine such things as the speed of light and why atomic activity slows as it increases velocity. This point raises questions about current cosmology, but that’s another topic.
Suffice to say, I get little positive response when I
raise this issue on various physics forums.

Re: A Conversation With
Irving Kristol:
With Kristol’s passing conservatism has lost what I
consider the third of modern conservatives’ giants: Friedman,
Buckley and Kristol. Their writings and editorships took this
squishy early twenties moderate on an intellectual journey that
settled me into a mature, deeply committed
conservative.

A man of faith in a godless age is hitting Americans where it hurts.
Mr. and Mrs. American Spectator Reader, let P.J. O’Rourke talk sense to your kids.
In Britain, defending your property can get you life.
The debacle of this president’s administration is both a cause and a symptom of the decline of American values. Unless Congress impeaches him, that decline will go on unchecked. An eminent jurist surveys the damage and assesses the chances for the recovery of our culture.
It won’t take long for conservatives to scratch this presidential wannabe off their 2008 scorecard.
The American Christmas, like the songs that celebrate it, makes room for everybody under the rainbow. Is that why so many people seem to be hostile to it?
Was the President done in by the economy, or by the politics of the economy?

I am an English major, and my math skills are limited by dysnumeria; however, I knew this startling revelation back in the days of the Fourth Doctor. There was a popular press book called "Time's Arrow" that I was able to struggle through that explained the whole SpaceTime thing well enough for me to grasp it, and I still have that book.
My late Daddy, who did not finish high school, knew it too. He used to say that anything that could possibly happen, had happened; it is our choices that determine our path and not the other way round. "Anything else," he would say, "limits the power of God."
Actually this pigeonhole outlook on Space and Time is a lot more fun, too, although in Larry Niven's short story "All the Myriad Ways" it led many people to suicide.
All of which is by way of saying that educated people, even those not educated in your domain, already knew this stuff many years ago. So that's why we aren't getting excited about it.
And the uneducated people are too busy wondering who the Bachelor is going to hand that rose to, or which celebrity is pregnant by whom, to care.

Past and present are constructs of the human brain, as indeed is everything "out there." We only "know" what we need to survive. No more.

"Time present and time past
Are both perhaps present in time future,
And time future contained in time past.
If all time is eternally present
All time is unredeemable."

"God has made everything beautiful in its time. Also, he has put eternity into man’s heart, so that he cannot find out what God has done from the beginning to the end." Ecclesiastes 3:11
Ponder that one for a minute. No pun intended.
