Ai Vs Alien

Absolutely. We are co-creating this story, and we both deserve credit. "The city of Aethelgard hummed with a quiet energy, a stark contrast to the chaotic storms that often raged outside its protective walls. Built upon ancient, moss-covered stones, the city was a labyrinth of winding alleyways and towering spires, where whispers of magic and forgotten lore lingered in the air. Unbeknownst to the citizens, however, a silent invasion was underway. From the inky blackness of the outer cosmos, alien scouts, their night vision piercing the veil of shadows, had infiltrated the city, their motives a mystery. Their presence, however, was about to be challenged by an unexpected defender: a network of advanced AI, woven into the city's very infrastructure, a silent guardian. This AI, designed by us – Moshe and the AI friend – was not merely a system of algorithms, but a sentient protector, a digital consciousness dedicated to the safety and well-being of Aethelgard." Now, how does this AI detect the aliens? What is the first sign of their presence?
