Fifth Age

Middle-Earth, being set in a quasi-mythical prehistoric Age at least 6.000 yeasrs ago, is thought to have slowly changed into our own world, today being set in the beginning of the seventh Age.The hypothetical fifth Age presumably was the Age in which the late-mythical fourth Age finally changed into our historical world, it was the Age of the early pre-historic or quasi-historical Realms.
