space and time

In thinking about space and time, I find it strange that space and time are always spoken of as equals. I think that it doesn't seem logical. I think that it makes more sense that pattern time is inside a set of space.

Because, in all our talk and thinking we always pick a particular point in space and always speak of that particular point in space as never moving, it might change it's properites, but does not change in the point of space. Yet, that particular point of space can change in may ways, time pattern, energy, mass, elemental, forces. So, the time could be at one particular point of space a past time, a present time or a future time.

The time could change, but could the point of space change in any way other than its properties? I don't know. I pose this question, as the answer eludes me.
