Adam In The Bible.

Before we can establish the age of the Universe, according to the Bible, we need to establish that Adam was a real person. There is a tendency in many cultures to consign Adam to fairyland.
Actually Adam is one of the most important characters in the entire Bible.
The name Adam is mentioned a total of 30 times in the Bible. The name Adam appears 21 times in the Old Testament, and 9 times in the New Testament.

We either accept that Adam was a real person, or throw away the entire Bible. By contrast:

The title "John the Baptist" is mentioned only 14 times.
Joseph, the stepfather of Jesus Christ, is mentioned 15 times in the Bible (7 times in Matthew, 6 times in Luke, and 2 times in John.)
Adam is therefore mentioned more than the title "John the Baptist" and Jesus' stepfather Joseph combined!

Supernatural evidence that Adam was a real person

There is supernatural evidence that Adam was a real person. The following is used with permission from The Genealogy of Noah in Genesis Chapter 5 (from "The Bible: An Extraterrestrial Message" by Chuck Missler).

The ancestors of Noah are recorded in Genesis 5. There are a total of 10 names, each with a specific Hebrew meaning. The English translations for the Hebrew words are recorded below.
