I remember reading somewhere in that time people were expecting apocalypses because of all the bad thing that was going around them in places like Egypt, mass raiding, mass slavery etc.. so looking for an an escape people started practicing ritiauals and John the baptist went around with h is follower Jesus preaching people his form of Judaism which Jesus later picked up.
There's no evidence for this, no.
It's true that in early first century Judea, many people did subscribe to apocalyptic religious views as a result of the times. It's true that many people proclaimed themselves The Anointed One, A Descendant of David that would come and reestablish an independent Israel for the first time in centuries. It's true that slavery was an extremely common and integral part of the Roman state. It's true that, at least according to the Gospels, Christ was a follower of John the Baptist and did not begin his own ministry until after John's execution by Herod.
That's all that's categorically or even likely true here. I'm not sure what was supposed to be happening in Egypt at the time, but as far as I know it was a perfectly productive and safe Roman Province ruled by an Augustal Prefect at the turn of the first century. I don't know what raiding you could be referring to either. Judea was not a frontier province, if it was being raided this would necessarily have to be a not-entirely-unfair characterization of Roman governance. The characterization of Christianity as a cult started by John and carried on by Jesus after his death is, again, something that is completely unsupportable and probably not something many people will argue for if only because of its lack of anything resembling a Neutral Point of View.
John the Baptist probably existed and was a religious figure in his time. He probably baptized Christ, because no one would have written the baptism in if it didn't happen because it is kind of embarrassing when your Messiah needs to be purged of sin by an itinerant preacher. He was almost certainly executed by Herod, either in 36 AD or earlier, depending on whether you find Josephus or the Bible more trustworthy.
Add in a crucifixion and you're also up to speed on everything we're mostly sure on about Christ.
Anything beyond this is speculation.
EDIT: and I am an idiot that needs to look at maps and think a bit before speaking. Thanks to Evan_TH for the correction.
Probably a better way to look at it is to consider John the Baptist an original. He was far more famous in his day than Jesus was. After his death, a cult grew up around John that could have been just as popular as early Christianity, and that is mentioned in Acts of the Apostles- which was written in the mid-60s A.D. Jesus, of course, started his essentially copy-cat ministry after John had been arrested- probably in late A.D. 34- and then ramped it up after John's beheading in early A.D. 35.
I would recommend Hagan's Year of the Passover for more on John.
