Hello Vicky, the Lord Jesus Christ is God, now incarnate. He is our Creator, the One who created the universe and everything in it, so He clearly predates our progenitors, Adam and Eve (He, in fact, is the One who created them) .. e.g. John 1:1-4, 14; Colossians 1:16-17, 2:9.
Jesus is God the Son, both from and to everlasting. As such, He is the eternal Divine Being with an eternal Divine nature, but He took on a second, human nature about 2,000 years ago at His Incarnation, when He was born as a human (bones, flesh and blood) baby to the Virgin Mary in the human line of King David of Israel (and as such, He is both King David's Creator AND his son, or as Jesus puts it in Revelation 22:16, He is "the root AND the offspring of David").
Jesus came here to save us from both the power of sin, and the penalty of our sins, as well from His Father's wrath in the age to come. He was born, lived and died on the Cross, for our sake, was resurrected and glorified, and He then ascended back into Heaven (where He came from) where He continues to live today as the God/man (though His human body is a glorified, eternal human body).
Here is what one of the four historic creeds of the church has to say about Him and His dual (Divine and human) nature.
The Symbol of Chalcedon
We, then, following the holy Fathers, all with one consent, teach men to confess one and the same Son, our Lord Jesus Christ,
the same perfect in Godhead and also perfect in manhood; truly God and truly man, of a reasonable [rational] soul and body; consubstantial [coessential] with us according to the manhood; in all things like unto us, without sin; begotten before all ages
of the Father according to the Godhead, and in these latter days, for us and for our salvation, born of the Virgin Mary,
the mother of God, according to the Manhood; one and the same Christ, Son, Lord, Only-begotten, to be acknowledged in
two natures, inconfusedly, unchangeably, indivisibly, inseparably; the distinction of natures being by no means taken away by
the union, but rather the property of each nature being preserved, and concurring in one person and one Subsistence, not parted
or divided into two persons, but one and the same Son, and only begotten, God the Word, the Lord Jesus Christ, as the prophets
from the beginning [have declared] concerning him, and the Lord Jesus Christ himself has taught us, and the Creed of the holy
Fathers has handed down to us.
