no its not blasphemy. God put a value on men higher thany any other creation apart from the angels.

my support that only humans have souls...in Genisis 1:20-25. " Then God said, let the waters abound with an abundance of living creatures, and let birds fly above the earth across the face of the firmament of the heavens. so God created great sea creatures and every living thing that moves, with which the waters abounded, according to their kind, and every winged bird according to its kind. and God saw that it was good. and God blesse them saying, be fruitful and multiply, and fill the waters in the seasm and let birds multiply on the earth. so the evening and the day were the fifth day. then God said, let the earth bring forth the living creature acording to tis kind: cattle and creeping thing and beast of the earth, each according to its kind, and it was so. and God made the beast of the earth according to its kind, cattle according to its kind, and and everything that creeps on the earth according to its kind. and God saw that it was good."-----creation of animals

Genisis 2:7 " and the Lord God formed man of dust of the ground, and breathed into his nostrils the breath of life: and man became a living being."

no where in the bible does it state that God breathed the breath of life into any other creature. God formed man from the dust, He then breathed our life or our soul into us. He merely spoke the animals into existence and so they were.
