Does the Bible Teach That Elijah Was Reincarnated as John the Baptist?

Questions about responding to someone who says the Bible teaches reincarnation when it says John the Baptist “is Elijah who was to come” in Matthew 11:14 and whether Matthew 24:36–44 is referring to the rapture.

• How should I respond to someone who says the Bible teaches reincarnation in the verse about John the Baptist being Elijah (Matt. 11:14)?
• Is Matthew 24:36–44 referring to the rapture, and if not, what’s the best way to convince someone it isn’t about the rapture?
