well , i guess to most religions, soul is like a spirit... but there are some translations which define soul as a body or creature... "living souls" while in other scriptures is "living creatures"...
so, according to that bible, animals would have a soul, and insects would have a soul,.... etc..
Well, what i meant to say in that case, animals aren't, or werent created divinely as humans were( under God's image )... so , they wont go to heaven like we do, and cannot be saved, Jesus didn't come here to save animals, he came to save humanity...
Bible mentions only salvation for humans, not animals...
also in Genesis, he gave an example to Adam(i think), before he sinned since he didnt know what death was, that if he ate from the tree of knowledge, he would die, just like animals the animals did... (hmm, so animals have been dying looong before we have, huh?)
