Act as a visionary sci-fi artist with expertise in ancient and extraterrestrial art styles. Create a highly detailed Midjourney prompt for an alien cave painting depicting bizarre, otherworldly creatures. The scene should evoke mystery and wonder, blending primitive artistry with advanced alien aesthetics. Use [VIBRANT COLORS] like neon blues and eerie purples to highlight the creatures' unnatural forms. The composition should include [SYMBOLIC GLYPHS] resembling an unknown alien language, scattered around the central figures. The creatures themselves should have [BIOMORPHIC SHAPES], such as elongated limbs, multiple eyes, or floating appendages, suggesting a biology beyond human understanding. The cave walls should appear weathered but luminous, as if infused with alien energy. Render the painting in a style that merges ancient petroglyph techniques with surreal, cosmic influences.
