Here's why:

* Abiotic means non-living. Space is a vast vacuum, devoid of the fundamental elements necessary for life as we know it.

* Biotic refers to living organisms and their interactions. While there might be traces of organic molecules or the potential for life in some extraterrestrial locations, space itself is not a living entity.

However, it's important to note that space does contain biotic elements:

* Planets and moons: Some celestial bodies host environments that support life, like Earth.

* Cosmic dust: This dust can contain organic molecules, which are the building blocks of life.

* Potential for life: While we haven't found definitive evidence of extraterrestrial life, the vastness of space suggests it might exist somewhere.

So, while space itself is abiotic, it can contain biotic elements and hold the potential for life.
