Mary, the mother of Jesus, was a human woman, and not any queen of heaven. Also, the goddesses of Egypt are never portrayed as being one goddess with many names, but separate goddesses. These are obvious stretches to create similarities that aren't there.
<Staff Edit>
Jesus' name was "Yeshua" or "Jeshua," depending on how you transliterate it, and was a form of the name "Yoshua" or "Joshua."
And here it becomes even clearer that you're trying to stretch similarities. Jesus did not take the form of animals or disguise Himself. What is evident is that His followers didn't recognize His resurrected body, but that is not the same.

This is just plain ludicrous. Of course the Egyptian mythology would have a god/goddess who could cast out illness and drive out evil spirits. At that time those things were commonly associated.
Jesus could do far more than cure illness and cast out evil spirits. He forgave sins, raised people from the dead, created wine from water, broke 5 loaves of bread and 2 fish and used it to feed over 5,000 people, cursed a fig tree so that it withered and died overnight, was the Creator (through Him all things were created), and much more.
And again, Jesus confirmed YHWH as the creator of heaven and earth and the only true God.

Without digging too deep into mythology, here are a few key differences:
1. Jesus, the eternal Son of God, was born in the flesh of the Holy Spirit through the human virgin Mary. Isis was born to a god and goddess who had sex.
2. Jesus, the eternal Son of God, had no beginning, but was in the beginning. Isis had a beginning when she was conceived and born
3. Jesus came to overthrow Death and Hades, and will one day cast them into the lake of fire. Isis created Hades (Osiris as the god of the underworld) when she sewed him back together and gave him an eternal "life" of undeath.
4. Jesus died for the sins of mankind and rose again on the third day. There is no such mythology around Isis.
These are just a few of the key differences. There are many more, such as the manner of His birth, those who attended it, the manner of his ministry, etc. But there is not time to go into all of them.
