This 问题 is discriminatory against Hindu pets. Maybe some 动物 know many Gods?? Forgot about them, didn't ya??? Heck, maybe some 动物 even believe in the Greek pantheon as their religious identity. /sarcasm
In all seriousness, I'm quite sure that 动物 don't grapple with existential issues. Which is what caused humankind to come up with the concept of God/Gods in the first place.
That's actually an interesting question. I honestly don't know. But if they do, they won't be able to tell us they know, because... they can't talk, of course.
Who knows...? We say 动物 have no conscious thought, which probably isn't wrong. However, I always say that we can never really know anything for sure... I interpret things a lot different than most people probably would.
My friend would say no - God only gave man that ability to know him.
I say yes - I think 动物 know a lot 更多 than we humans give them credit for. I also think that when I read the bible out loud to my 狗 - they seem to know that I am 阅读 something important and they settle down.
