Answer and Explanation:
The Thomas Theorem shows that reality totally depends on people's beliefs about it. That's because the Thomas Theorem claims that if people define something as real, that "something" will be real within its own circumstances. In this case, the Thomas Theorem claims that belief in Santa Claus makes it real, within very specific circumstances and we can recognize this, as during Christmas we see Santa Claus in so many places that this vision creates a circumstance,where it becomes real.
