Random Symbol I found?!

[Mahoo]

There's allot of symbols around from Pagan to Greek and dadeeda but I have found something that's trippy and it's on a door and there is no way in hell this could have been hit by something and created because it's too precise but at the same time it would be to hard to carve in any way. Now I'm very confused as to why its been on my door for all of my life and I hope it's not a bad luck symbol cause I haven't had a great life and I was wondering if anyone could tell me if it meant anything?

I took a photo of it here http://img35.imageshack.us/img35/8195/pa260117.jpg

Hi, I have a couple of questions, since it's not obvious in the photograph.

Where one your door is this mark? Can you tell how it was made? What is your door made out of?

And one that has nothing to do with the photo, why do you think it might be a Pagan symbol?

Thanks for answering these questions for me, I'm super curious about this, and may even be able to help in some way. :D
