Of course, I agree that a number of these works came out around that time; however, apocryphal writings were written across a huge span of time; we have a few that were dated to be around the 4th century or later.
I know their authorship is also questioned, but they read genuine.
Depends on what book you’re checking. In some books, Jesus is a bit close enough to the canonical Gospels - though at times with a bit more ‘extravagance’ on His miracles; in others (say, the Infancy Gospel of Thomas), the boy Jesus is a ‘holy’ know-it-all brat who for example kills off the boy who bullied Him with His words and strikes blind the people who came to Joseph’s house to complain about it, as well as ending up teaching the teacher who offered to teach Him His letters. Still others (especially in overtly Gnostic works such as Pistis Sophia, the Gospel of Judas, or the Books of Jeu), have Jesus as this guru who spoke in incomprehensible jargon and who is sometimes accompanied with much showy fanfare:
After he rose from the dead, his twelve disciples and seven women continued to be his followers, and went to Galilee onto the mountain called “Divination and Joy”. When they gathered together and were perplexed about the underlying reality of the universe and the plan, and the holy providence, and the power of the authorities, and about everything the Savior is doing with them in the secret of the holy plan, the Savior appeared - not in his previous form, but in the invisible spirit. And his likeness resembles a great angel of light. But his resemblance I must not describe. No mortal flesh could endure it, but only pure, perfect flesh, like that which he taught us about on the mountain called “Of the Olives” in Galilee.
And he said: “Peace be to you, My peace I give you!” And they all marveled and were afraid. The Savior laughed and said to them: “What are you thinking about? Are you perplexed? What are you searching for?”
Philip said: “For the underlying reality of the universe and the plan.”
The Savior said to them: “I* want you to know that all men are born on earth from the foundation of the world until now, being dust, while they have inquired about God, who he is and what he is like, have not found him. Now the wisest among them have speculated from the ordering of the world and (its) movement. But their speculation has not reached the truth. For it is said that the ordering is directed in three ways, by all the philosophers, (and) hence they do not agree. For some of them say about the world that it is directed by itself. Others, that it is providence (that directs it). Others, that it is fate. But it is none of these. Again, of the three voices I have just mentioned, none is close to the truth, and (they are) from man. But I, who came from Infinite Light, I am here - for I know him (Light) - that I might speak to you about the precise nature of the truth. For whatever is from itself is a polluted life; it is self-made. Providence has no wisdom in it. And fate does not discern. But to you it is given to know; and whoever is worthy of knowledge will receive (it), whoever has not been begotten by the sowing of unclean rubbing but by First Who Was Sent, for he is an immortal in the midst of mortal men.*”
