According to the bible the word "Reincarnation" does not exist. The bible is a holy book which was written through God's guidance and the help of the holy spirit and of course the bible does not lie. Reincarnation is not biblical and does not agree with the teachings of the bible.
The book of Hebrews 9:27 shows that human beings live only once, die once and face the judgement; there is no second chance to come back to earth as another person or creature. Some people misunderstand certain bible passages such as the coming of Elijah and wrongly use it to support the idea of reincarnation. According to the bible, Elijah did not reincarnate as John the Baptist, rather John came in the spirit and power of Elijah, which means that he carried similar mission, not the same soul.
As christians, let's not believe on what does not exist. The idea that a person dies and reincarnate again in another body contradict God's word. So reincarnation is not biblical because it is not possible.
God bless you all 🙏
