Earth-89 was one of the many universes in the multiverse. Earth-89 was destroyed by antimatter at the beginning of the Anti-Monitor Crisis. When the Paragons and the Spectre created the new multiverse, a new universe was created, which is said to be identical to this universe. The number 89 references the year the first live-action Batman film was released into theaters in 1989. The Flash of Earth-TUD13 would later get this Earth's timeline mangled with his own in a version of 'Flashpoint'.
