I will tell the Tibetans to believe what they will.
I am agnostic, that is I don't believe in any God or religion.

Gautama Buddha (c. 563 BCE/480 BCE – c. 483 BCE/400 BCE), also known as Siddhartha Gautama
No written records about Gautama were found from his lifetime or some centuries thereafter.
Various collections of teachings attributed to him were passed down by oral tradition and first committed to writing about 400 years later.
Scholars are hesitant to make unqualified claims about the historical facts of the Buddha's life. (Edit: except the Indians)

Yes you read it correctly, there are no records to verify anything but hearsay.
Believe what you will and I respect that, but don't make claims based on hearsay onto non believers.
