Every Prophet shows miracles to his own people. Such as Jesus' miracle was raising the dead and healing people; Moses turning his stick into a snake.

These kinds of miracles fit the minds of those people in that time of ignorance, that's why when they saw Jesus born miraculously some of them worshiped him as the son of God after he left this world and they forget that Adam was created without a father and a mother,
it was a test from God to them.

You can't see these miracles anymore because they have gone with their people. The same goes when God sent another prophet with new miracles to confirm his message the same message the other prophets came with from the one and only God "to worship him".
