T-Race As Old As Lightness

The GA military research teams lately found out that the T-Race is actually as old as the Lightness, however as we still know very little about both species it is believed that this is mostly untrue. Still it has been confirmed that both of them are ancient races and presumably have met each other before. T-Race on the other hand still claims that they have had no contact with the Lightness before and that they are younger race than the Lightness. The experts at GA military research department claim otherwise; they believe that the T-Race is lying on this thing, however they do not know why.
