Yes. There was a chap called Jesus of Nazareth living around in the Roman province of Judea in the early ADs. And he was crucified by the Romans, although apparently the chap in charge of that area, Pontus Pilate, showed sympathy to Jesus.
Dude even our prophet had the same miracles but he never asked us to worship him. He told there is only one God in this universe.
yes he did plenty of times. he said 'i and the father one', 'the lord is in need of this' when referring to himself, 'before abraham was i am' using the present tense to show his eternal nature, 'no one comes to the father except through me', 'i am the truth, the way and the life' that speaks for itself and many, many more, especially mirroring things that god said in the old testament. someone else already said he forgave sins which only god can do. he also said he had all authority in heaven and on earth. only god can have all authority in heaven. in christianity there is also only 1 god
