Christ's birth was told by Micah a
prophet, five hundred years before,
saying......
"But thou, Bethlehem Ephratah, though
thou be little among the thousands of
Judah, yet out of thee shall he come forth
unto me that is to be ruler in Israel; whose
goings forth have been from of old,
from everlasting." Micah 5:2

Thus Jesus existed before his birth here
on earth.

And it prdicted that he would be born in
Bethlehem.
