Was Mary Immaculately Conceived? What do you think of what I found below?

The Bible says that Jesus was born of a virgin- God said it I believe it- Mary was not sinless, by the way- no one is except Jesus. She was a young girl who loved the Lord and was selected for her love and devotion to Him, but not for her being sinless. I don't know way the Catholics chose not to believe this from the beginning since it is in scripture, however, today some worship Mary. This should not be, We can honor her as being the mother of Jesus- but Jesus alone is to be worshiped,
