Time as the Fourth Dimension

This should have been more obvious to me.

In order for our eyes to see something it must have four dimensions: 1. width, 2. depth, 3. height, and 4. exist now. That is why I cannot see the house that burned down before this one was built. It had three dimensions, but it does not exist now. Paradoxically, the building that will be here when this house burns down will have three dimensions, but cannot be seen because it hasn't yet been built, so it, too, does not exist now.

So what about this seeming eral perspective?
