Actually, except for most Fundamentalist Christians and some groups like the Mormons and Jehovah's Witnesses, the rest of Christianity and all Jews acknowledge that there are no foretelling of events by the prophets in the Scripture, such as predictions.
Jehovah's Witnesses often use the following to explain what a true prophet can do in refrence to foretell the future:
When a prophet speaks in the name of the Lord, if the word does not come to pass or come true, that is a word that the Lord has not spoken; the prophet has spoken it presumptuously. You need not be afraid of him.--Deuteronomy 18:22.
But in reality, it is not speaking about predicting the future. Take for instance the prophet Jonah, whose message to Ninevah from God did not come true at all:
"Forty days more and Nineveh shall be overthrown!"--Jonah 3:4.
Did that make Jonah a false prophet? According to the way Jehovah's Witnesses define prophecy and prophets and Deuteronomy 18:22, the answer is "yes." "Uh, no, uh, what?"
But the word "prophet" in Hebrew means "spokesman" and not a foreseer of events. In fact it if forbidden by the Mosaic Law for a Jew to attempt to forecast the future by any means.--Lev 19:32, Deut 18:9-12.
There are no "prophecies" in this sense, whatsoever, about anything, anywhere in the Bible, let alone about the Messiah.
The Jewish concept of the Messiah came about after the last of the books of the Prophets was written, after the Maccabean Revolt which ended in 160 BCE, the events which gave Judaism the first Chanukah celebration. These events led to the Jews crowning a member of the Maccabees as king of the Jews.
But the family line of Judas Maccabeus was not in the line of David or of the tribe of Judah, but of the tribe of Levi. And the Maccabees became oppressive. They aligned with Rome and married into a family known as the Herods which took over from the Maccabees.
Due to the oppression, the Jews began to study the Jewish texts and realized that the prophets and the Psalms mentioned that God had promised that a son of David was supposed to be anointed as their king, not someone in the line of Levi. So they began to pray for God to redeem them from the hands of the Herods and the Romans, to bring the promised Son of David, the promised anointed (in Hebrew, Masiach or Messiah).
A theology began to be built around many of these texts, though none of them are "prophecies." There are NO texts in the Bible that say: "There shall come a Messiah..." or "The Messiah shall come that will do this and that..." The first time the Jews used such expressions as a concept were in the Gamara, then in the Mishnah, which came to be transfered into writings of the Talmud.
The fullest concepts of the Messiah were developed by the early Christians themselves, not the Jews, which is why the Jews rejected Jesus as the Messiah. The theology of the Messiah is found still developing in the writings of the Church Fathers.
Simultaneously at the time, the Jews began developing their own theology to counter what the Messiah should and should not do.
The use of Genesis 3:15 in reference to Jesus does not come from the Jews but the Church Fathers, in the writing of St. Irenaeus entitled, "Against Heresies" in which he states not that Jesus is predicted by the verse but that it is a divine illustrative drama in which God takes on human nature in Jesus by means of Mary to battle Satan the Devil.
For more information on that, you will want to look up that writing in the Church Fathers.
