"Conspired?" You're closer then you think, considering that Matthew and Luke appear to have used Mark as a source.
You laugh a lot, don't you? I'm glad you have a sense of humor, since you seem to have so little else going for you.
Let's consider a few non-Canonical texts. Hm, let me see ... The Gospel of Thomas, the Gospel of Judas, the Shepherd of Hermas, the Infancy Gospel of Thomas, the Acts of Paul and Thecla, and the Apocalypse of Peter. Those will do for a start. Do you think that these books form an accurate portrait of Jesus. For example, do you agree with the author of Thomas that Jesus espoused Gnostic philosophy? Do you think that as a child, he struck people dead on a whim?
... You don't?
You think the authors of the gospels, acts, and apocalypse I just listed made stuff up?
And yet when I suggest that the authors of the canonical Gospels also made things up, you act like it's the funniest thing in the world, and you need only (poorly) rephrase my suggestion for every body to see how ludacrous it is.
You really haven't thought this all the way through, have you?
