[Nosterrex]

You are asking an epistemological question. How do I know God's mysteries? God has revealed himself in His Word and that Word is found in Holy Scriptures. God breathed into Adam's nostrils and he became a living soul. Man is created in the image and likeness of God. Animals do not have souls, and their existence ends with their death. That is the primary source of my knowledge of God's mysteries. Where Scripture speaks I speak, and where Scripture is silent, I am silent. Now, I ask you. How do you decide whether animals have souls to not, or for that matter, human beings?
I do believe that a rational answer can be found within nature itself. Human beings have a conscience in which they are concerned about morality. Animals do not. No one ever heard of an immoral cow or dog. Animals do not care about eternal things, nor do they reflect upon their death. I would suggest that all of these are indications of man's soul. Btw, I did get an A in science class.

[RegulatorCountry]

But God giveth it a body as it hath pleased Him, and to every seed his own body. All flesh is not the same flesh; but there is one kind of flesh of men, another flesh of beasts, another of fishes, and another of birds. There are celestial bodies, and bodies terrestrial: but the glory of the celestial is one, and the glory of the terrestrial is another. There is one glory of the sun, and another glory of the moon, and another glory of the stars; for one star differeth from another star in glory. So, also is the resurrection of the dead. It is sown in corruption; it is raised in incorruption; it is sown in dishonor; it is raised in glory; it is sown in weakness; it is raised in power: it is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.
