Well I ask this question because
1. nobody has entered the sun before, we only know it's content and the fact that it's is million Times bigger than the earth.

2. in genesis 1:15, the bible stated clearly that the lights of the heaven gives light upon the earth. we know that the sun gives us light.

3. some people in the bible did not die, like Elijah. they went up with their physical body to heaven, even the transfiguration points to the fact that 3 men just came from the sky and talked with Jesus.

4. Jesus ascended into heavens.

5. some people have claimed to see the cross why standing on the earth

so could the sun possibly be heaven?.

Sun causes skin cancer. Maybe it really is heaven.

Could be. Since the rapture requires levitation.

There are billion of Suns (stars) in the galaxy. So, even though we cannot actually count the number of stars in the galaxy, we can estimate the number of stars in the galaxy as roughly 100 billion (100,000,000,000). So heaven could be any of those Suns bruh... Ahhahhhah
