Extensive studies of children four years old and under who remember details (which were verified) of past lives often remember being being born many times, in different genders.
Adults under hypnosis also remember numerous past lives, including details, names, places, and in all these cases, when both the young children and adults returned to the locations of their most recent past life..sometimes only months or weeks before, they recognized family, remembered conversations, etc. beyond all possible doubt of random chance.
Many of the children insisted they are the ones who chose which gender in which to reincarnate, and that they would wait for the correct gender to be conceived in someone before inhabiting the fetus. Others said that after being a particular gender several lifetimes in a row, if they were then born into a different gender, they had trouble adjusting. Some said that's when they would become transgender.
As for people using the Bible as authority, remember that the ancient Sumerian manuscripts carved on the stone walls in Babylon, tell the same stories as the Old Testament, using almost the same names, except that it was written 2000 years before the Bible.
In the Sumerian version, though, humans were genetically engineered by the Sumerians, who came to earth to mine gold and combined their DNA with human ape DNA to create obedient workers who wouldn't question authority. Pictures on the wall even show the Sumerian researchers in the genetic labs with beakers, and show rockets and flying machines similar to our current ones.

If you take the Bible as your authority, perhaps you don't realize that the Old Testament punishment for breaking the Ten Commandments, even for picking up sticks on Saturday, was DEATH BY STONING.
In the New Testament, women are commanded to wear veils, never cut their hair, stay at home, have children, don't speak in church, and never have authority over men.
