For example, the infinite set of natural real numbers seems to exist, which is to say that there is an infinity of natural real numbers existing even now, and there is none of them which do not yet exist.
There are an infinity of points on a line segment.
It is logically possible that reality has an infinite history of cause and effect (i.e. extending "backward" through the big-bang), and that it will have an infinite future.
In what sense could an infinity of simultaneously existing things exist together as a finite thing?
Regarding this portion of the OP, it is not logical that there are an infinite history of causes and effects. The future is potentially infinite but never will be.
