Are Viruses alive?

In the fields of biology a common question constantly emerges, are viruses alive? This is a touchy gray area within many aspects of sciences. My opinion is no, viruses are not alive. A virus may contain many abilities that reside within homeostasis, one such being replication. How can something that is not alive procreate or make more of itself. One way would be bacteriophage. The bacteriophage attach to a cell and infect it with viral Deoxyribonuecleic acids. The viral Dna merges with the cells dna through meosis changing the cell's functions and making it produce more bacteriophage. So how can the virus not be alive?.. Its only ability is to infect mutate reproduce and repeat. They have no way to regulate there systems, they dont breathe these are just two aspects of homeostasis they dont follow. Thus they cant live.
