You can think of it as a fruit from a fruit tree, something growing from a substrate. If the fruit had a beginning, it must be finite in size. Time for our universe starts at the BB, IF our universe had a beginning. A singularity in this context is a physical process taking zero time which results in an infinite spatial extent. This can't happen IF our universe had a beginning since inflation and expansion occur at finite rates for finite times. The Multiverse never began, so whatever infinities it has, if any, didn't occur in finite time.
