However, you dont need to think that way simply because we have a very early church father, Clement of Rome (30-100 AD) who wrote extensively. He knew Paul, Luke and Peter.
What we really have is tradition upon tradition, often contradictory and hundreds of years separated and motivated by the claim for apostolic succession.
The work called 1 Clement is anonymous, it's time of writing is largely assigned due to traditional dating of related writings. The author doesn't claim to have known Peter or Paul only saying they had died and went to heaven. They represent the start of a long listing of OT characters who died. It's pretty doctrinally neutral, apart from pretty stern warnings that women must be obedient. The oldest copy we have dates to the 11th century. It was regarded as canonical by many for centuries. 2nd Clement is a similarly anonymous work often dated to the same period, again because of tradition. Some of the later Church Fathers dismissed 2 Clement because they didn't like some of the content.
The author of 1 Clement included some mythology in his praise for creation:
1Clem 25:2
There is a bird, which is named the phoenix. This, being the only one of its kind, liveth for five hundred years; and when it hath now reached the time of its dissolution that it should die, it maketh for itself a coffin of frankincense and myrrh and the other spices, into the which in the fullness of time it entereth, and so it dieth.
1Clem 25:3
But, as the flesh rotteth, a certain worm is engendered, which is
nurtured from the moisture of the dead creature and putteth forth wings. Then, when it is grown lusty, it taketh up that coffin where are the bones of its parent, and carrying them journeyeth from the country of Arabia even unto Egypt, to the place called the City of the Sun;
1Clem 25:4
and in the daytime in the sight of all, flying to the altar of the
Sun, it layeth them thereupon; and this done, it setteth forth to
return.
1Clem 25:5
So the priests examine the registers of the times, and they find that it hath come when the five hundredth year is completed.
