2. Isn't Time just a human made measure of change in organic & inorganic matter?

In that sense, humans conceived the reality of all matter falling apart. Only infusion of energy (eg the sand castle) slows but never ends entropy. Only spirit is timeless, since it is not matter.

3. The nature of time is not a settled scientific concept

but our perception of time is supported by the 2nd law of thermodynamics. Here is another video which discusses the universe and space and time as science currently understands it.

There are the black hole and information concepts that Stephen Hawkings developed that are also fascinating. I believe I posted another one from Brian Cox which touches on it, it might be the one where he mentions Carl Sagan. Look for his name in the title.

4. Thanks. Cox is always interesting.

He also frequently discusses the concept of infinity.

Another way of saying things about this...

We HAVE to perceive time because we are made of matter that's organic and spirit. And so we humans' organic matter systems have developed the consciousness to notice the death of other organic matter, and the breakdown of inorganic matter (rocks to soil, etc) in time, because both kinds of matter are made of "parts," which take up space.
And so because of matter, space and time exist.

And so we humans of conscious organic matter have perceived, then measured, time from microseconds to light years.

We've also perceived that there is such a thing as no matter beyond time and space, which is spirit, which science doesn't deal with, though many scientists acknowledge its existence.

5. I enjoy your (human) persective on this. What would a non-human sentient organism think?

Is "spirit" only a human concept? Again, like so many properties we give to ourselves, perhaps earthworms and other organic organisms have their own sense.

I'm not going to ask one of those silicon "AI" bots what they think about this.

6. Another interesting watch. Please keep them up!
