This is a question that many different religions hold views on.
Thankfully, for the believer, God's Word gives us a glimpse of what heaven will be like. Regardless of what our language is able to describe it as, it doesn't come close to the reality of what heaven will truly be like.
Here is how God's Word describes heaven though.
There is often another question associated with heaven, where do animals go when they die? Will there be animals in heaven?
The Bible never talks about animals having souls, that is what is unique about man from all the other animals. We are set apart, made in the image of God. Animals do not have a soul, they are not on the same level of humans. But just as in the Garden of Eden there were animals, my personal belief is that there will be animals in heaven as well. I believe that the Garden was supposed to be a glimpse of heaven. There will be a New Heaven and a New Earth, and I believe that on this New Earth there will be animals as well.
