Not only did Jesus NOT pre-exist, he didn't exist or "post-exist" either.
While there may - or may not - have been a historical Jewish revolutionary who was the object of a massive historical publicity campaign and con-job, there certainly NEVER was a "Son of God."
Why? Because there is NO god to "father" such a Son.
Religion is a snare and a racket - truer words were never spoken!
Only you can set you free.
