do you own a car or a current house, and how did that get its value now?  Bitcoin is also like that, the current bitcoin price is created because of people's trust in the market, when trading occurs on DEX, CEX or P2P, the flow of money going in and out will automatically create prices.

Bitcoin is a decentralized cryptocurrency, which means that the price and even circulation cannot be controlled and manipulated by anyone, even me, you or the government, everything happens purely on supply and demand.
