Vanderhoven7,
It's indeed strange that no one else saw Jesus ascending to heaven except a handful of his disciples.
Even if you are not looking upwards and are looking straight ahead it’s still possible to see an upward motion rising towards to sky. Yet no one else saw Jesus’ ascension only a handful of his disciples did.
It's even stranger how every eye will see Jesus when he returns yet only a handful of his disciples saw him when he was ascending to heaven (Revelation 1:7).
ALSO, if a person claims to be the son of God then most naturally there will have to be supernatural events to convince people of this since anybody can claim to be God's son.
Jesus' ascension to heaven would have been a very easy opportunity for God to capitalize on in order to convince & convert the Jews.
If they weren't interested in being converted, we should at least hear reports about it from the Jews if they were eyewitnesses a part from what is stated in the Bible.
