greenmanSeeing as

In spoken English especially, the conjunction seeing as is very commonly used instead of since or "in view of the fact that".

 

E.g.

Seeing as you paid for the last round, I'll get this one— Ya que pagaste la última ronda, yo te invito esta vez

It's too soon for thumbs-up selfies, seeing as it only happened 70 years ago—Es demasiado pronto para selfies con el pulgar levantado, visto que sucedió hace solo 70 años
