Without wading in to all of your points, I'll say that the ancient Church is not as stupid as you're assuming. The ancient troparion to the Nativity of Christ makes reference to the God of the Universe using the astrologers' veneration of the stars to show them Jesus Christ, the Truth.
"Thy Nativity, O Christ our God, has shown to the world the light of wisdom.
For by it those who worshipped the stars were taught by a star to adore Thee, the Sun of Righteousness,
And to know Thee, the Orient from on high.
O Lord, glory to Thee!"
This tired trope that "muh pagan holidays nearby Christian feasts so it turns out Christianity is all fake" lacks both knowledge and imagination, and is really embarrassing for the people who advance it. A study of these issues as the Orthodox Christian Church teaches them will be deeply rewarding to someone seeking Jesus Christ.
