There is no direct evidence that ancient Egyptians influenced the Mayans, Incas, or Aztecs. While these civilizations share some similarities, such as pyramid structures, religious rituals, and advanced engineering, most scholars believe these developments arose independently.
The vast geographical separation between Egypt and Mesoamerican civilizations, combined with the lack of significant evidence of direct contact (such as shared artifacts or writing systems), makes it unlikely that Egyptians influenced these American civilizations. Instead, it seems that similar solutions to societal and architectural challenges were developed independently across different parts of the world.
Some alternative theories suggest ancient trans-oceanic contact, but these ideas remain speculative and are not widely accepted in mainstream archaeology.
