>didn't have time in his life to find Jesus
"'All know the truth about God because he has made it obvious to them.''
For ever since the world was created, people have seen the earth and sky. Through everything God made, they can clearly see his invisible qualities—his eternal power and divine nature. So they have no excuse for not knowing God.
Yes, they knew God, but they wouldn’t worship him as God or even give him thanks…
-Romans 1:19-22 (NLT)
But more specifically to your question about age - it seems that God considers 19 years old to be the last year anyone can be 'too young to know any better':
Then the LORD said…You will all drop dead in this wilderness! Because you complained against me, every one of you who is twenty years old or older and was included in the registration will die. You will not enter and occupy the land I swore to give you. The only exceptions will be Caleb son of Jephunneh and Joshua son of Nun. You said your children would be carried off as plunder. Well, I will bring them safely into the land, and they will enjoy what you have despised. But as for you, you will drop dead in this wilderness… - Numbers 14:26-32 (NLT)
I watched as the Lamb broke the sixth seal… Then everyone - the kings of the earth, the rulers, the generals, the wealthy, the powerful, and every slave and free person - all hid themselves in the caves and among the rocks of the mountains. And they cried to the mountains and the rocks, “Fall on us and hide us from the face of the one who sits on the throne and from the wrath of the Lamb. For the great day of their wrath has come, and who is able to survive?”
Revelation 6:15-16
Evidence is mounting that the original 'gospels' were written in Hebrew.

Bible scholar Nehemia Gordon explains how he discovered Hebrew manuscripts of Luke and John in the 'junk bin' archives at the National Library of Israel. These manuscripts were never shared with the public before this was aired and are particularly interesting when compared to the Greek text. They are also another proof that the name of God is unequivocally Yehovah and clearly show the pronunciation of the name Yeshua.
