How old is our wonderful planet Earth? 6000 years?

[TonyGosling]

Irenseus also is, as has been stated, a true Chiliast, and takes the 1000 years of blessedness in a literal sense.

As the world was created in six days, and as one day with the Lord was as 1000 years, the world would last 6000 years; and, as a day of rest followed on the six days of work, so there would follow 1000 years of rest on the 6000 years of the earth s history.

After this temporary kingdom the final judgement would follow and the new heaven and the new earth.
