Did Egyptian texts call Aten the only god, and are they older than Gathas?

Research question: Do Egyptian Atenist texts describe Aten as the sole god, and how do scholars date them relative to the Gathas?

The records show that Akhenaten refers to his single god as 'Aten' and never simply calls him 'god' (rtr) ¹. This usage suggests the sole deity is named rather than generically described, which bears on the first part of the question ¹. The verified facts do not state outright that Atenist texts describe Aten as the sole god, so that point is only indirectly supported ¹. Nothing in the available facts addresses how scholars date these texts relative to the Gathas, so the second part of the question cannot be answered from this material ¹. The only fact supplied gives no publication date, so its recency relative to October 2026 cannot be determined ¹.
