Why did us establish a form of democratic government instead of a theocracy or monarchy?

The United States established a democratic government primarily to ensure individual freedoms and prevent the concentration of power in the hands of a single ruler or religious authority. Influenced by Enlightenment ideas, the Founding Fathers believed that a government should be based on the consent of the governed, allowing for representation and accountability. This structure aimed to protect citizens' rights and promote equality, contrasting sharply with the hierarchical nature of monarchies and theocratic systems. Ultimately, the goal was to create a system that could adapt to the needs of its people while safeguarding against tyranny.
