¶ When they had heard the king, they departed; and, lo, the star, which they saw in the east, went before them, till it came and stood over where the young child was. 10 When they saw the star, they rejoiced with exceeding great joy. Mathew 2:9-10
The wise men never visited the manger.
The "star" was not a star since a star could not pinpoint a house.
If they came from the east the star was not in the east.
The "star" did not appear in the east at the time of Juesus' birth unless it took them two years to get to the house. It is generally believed Jesus was about two years old at the time of their visit.
There is not evidence there were only three becase there were three gifts.
