Firstly, apologies if a similar thread already exists. I would have searched but alas there's no option to search

Anyways,
One thing that always puzzled me about when God decided to come to earth in human form. He didn't really do anything 'Godlike'. The God of the Old Testament had no reservations in showing his power. Not only that but his actions were witnessed by thousands, even if only recorded by a few. Jesus on the other hand did comparatively nothing. Sure he walked on water, changed water in wine, calmed a storm but all these were done in front of a small select group of people. He was the God who created the world and yet that was all he did, stuff which, if it were performed today, nobody would actually believe.
Why not do something that couldn't be questioned, such as tell us about what diseases actually were,the dinosaurs, the stars, how to cure cancer, how to predict earthquakes, status of women, indicate when the next eclipse would be,or the next sky-time 'fireball', fertilize a desert, show some cool physics trick that defied common sense at the time etc etc?
Instead He insured that there would be ambiguity and doubt, by preaching stuff which was already preached a thousands times over by the various other religions. If He were the creator of the heavens and the earth then surely He would have actually shown us something beyond any reasonable measure of doubt?
Go on tear me apart
