Do I have the right to demand proof of the opposing bids?

I need some good advice here. I am buying a house with four bedrooms and 2 bathrooms. It's located in Los Angeles, California. My family loves this house so I want to buy it as soon as possible. But, I have reason to believe that the seller's agent was not truthful about the opposing bid for this property. I am suspicious he made up bids to drive up the price I eventually offered. Do I have the right to demand proof of the opposing bids? What can I do to solve it?
