'Ages' in the Bible

A generation comes and a generation goes, but the earth remains the same through the ages.

Can one say about anything,“Look, this is new”?It has already existed in the ages before us.

He has made everything beautiful and appropriate in its time. He has also planted eternity [a sense of divine purpose] in the human heart [a mysterious longing which nothing under the sun can satisfy, except God]—yet man cannot find out (comprehend, grasp) what God has done (His overall plan) from the beginning to the end.
