I thought this was supposed to be a non biast forum.

Jesus was ressurected 3 days after he was crucified.

Are you saying an age could be 3 days?

By the way the Wheel of Time works it is consistent that we are the First Age of the wheel. People who can channel gained the ability from Tamyrlin who was the first channeler given his power by the Creator. That means that they have to lose their ability to channel before they can get it back.

Losing it signals the end of the 7th Age and them getting it back signals the end of the First Age.

Rand went through the Portal Stone and saw alternate universes. Egwene went through the Accepted Test and saw possibilities of her future. Aviendha and Moraine went through the Rings in Rhuidean and saw every choice she could have made in different ways. Rand and Mat went through the Red door leading to the Tower of Ghenjei and the Aelfinn.

RJ could have gone through any of these to gain his knowledge of Randland.
