Ancient history of humankind or science-fiction?

Amscusat is a teenager who, according to the custom of the space-time he lives in, shares his studies, friendships and adventures with a wide variety of humans, animals and plants.

Despite the advanced technology that characterizes his time, his adventures are framed in a war scenario, a ruthless, ongoing conflict underway since time immemorial. The enemy, the principle opposing the evolution of any intelligent species, relentlessly pursues the destruction of any planets which get in its way.

Is this the story of an indecipherable future or the journal of a forgotten past?
