The concept of a "universal God" or a single deity that is recognized and worshipped by all cultures and religions is not present in human history. Different cultures and civilizations have developed their own beliefs and deities, often with different attributes, characteristics, and mythologies.
Throughout history, various cultures have had their own dominant gods or deities. For example, in ancient Egypt, the sun god Ra was considered one of the most important deities. In Greek mythology, Zeus was the king of the gods. In Hinduism, Brahman is often regarded as the ultimate reality or divine essence.
It's important to note that the idea of a universal God or a deity worshipped by all people regardless of culture or religion is a more recent concept found in certain monotheistic religions such as Christianity, Islam, and Judaism. These religions believe in a single, all-powerful God who is considered universal and worshipped by their respective followers. However, it is still not accurate to refer to any one of these deities as the "first universal God," as their concepts and worship emerged within specific historical and cultural contexts.
