Time is a sequence of (x, y, z) coordinates?

Time is a sequence of (x, y, z) coordinates?
What?
No.
Time is a single dimension  ergo three coordinates are not needed.
Be so kind as to point out a mistake in my thinking.
"We do not live in 4dimensional space because such are the rules of geometry, but according to the rules of geometry, threedimensional space is one of the facets of fourdimensional space, and therefore, according to the rules of geometry, we must live in fourdimensional space, and if we go deeper, then fourdimensional space must be a face fivedimensional space, and fivedimensional space should be a facet of sixdimensional space, which means that you and I should live in sixdimensional space and perceive as fivedimensional and fourdimensional objects, and not projections of fourdimensional objects in threedimensional space, but for some reason we do not perceive them, which means is it that we live only in threedimensional space and there is no fourdimensional or fivedimensional space, or sixdimensional and higher in terms of space?"
I understand that physics does not lend itself to exclusively logical structures**.It is more a case of fitting potential models to existing or future observations.While there could in principle be any number of spatial and temporal dimensions these have only been observed as 3 spatial and 1 temporal so far.
The relativity model uses these but I understand some models attempt higher numbers without as far as I know explaining any phenomena not already covered by General Relativity.
** by which I mean that nature does not behave in a way that we may reason using logic that it should.
It is what it is ,as we find it.

Which part of "Time is a single dimension  ergo three coordinates are not needed" did you not understand?
Nope. (And if that's a quote  as indicated  then you should provide the source)."We do not live in 4dimensional space because such are the rules of geometry, but according to the rules of geometry, threedimensional space is one of the facets of fourdimensional space, and therefore, according to the rules of geometry, we must live in fourdimensional space, and if we go deeper, then fourdimensional space must be a face fivedimensional space, and fivedimensional space should be a facet of sixdimensional space, which means that you and I should live in sixdimensional space and perceive as fivedimensional and fourdimensional objects, and not projections of fourdimensional objects in threedimensional space, but for some reason we do not perceive them, which means is it that we live only in threedimensional space and there is no fourdimensional or fivedimensional space, or sixdimensional and higher in terms of space?"
No, wrong. If time could be represented a series of points, or as a line in space, then it would not be independent of spatial coordinates and could not be a coordinate in its own right. Being an independent 4th coordinate means it can't be dependent on spatial coordinates.

Don't they talk about the time and spatial dimensions (right terminology?) flipping when conditions like singularities occur?
Time could become space and space become time?
Pretty sure I have heard that at least as a theoretical possibility.

Everything screams it is impossible.Unless there is the faintest evidence or observation that something remotely similar has occurred then it is clearly just a talking point.
As they say ,extraordinary claims require extraordinary explanations(edit:should be "require extraordinary evidence" ,I think)

I mean that when traveling to the event that I need, let's say in an event that is approximately equal to an event that has already happened, approximately because in the event I will go to, I myself will be in this event a distinctive feature of this event relative to the one that happened, proof that I am from the future, I do not know what can serve, what do you think can serve?
To my mind the scenario (at least on the macro level) is so bizarre as to not merit any consideration.
The quantum level might well be a very different scenario but that is not what you are apparently talking about.
