When we look at the history of religions, we can find out that older religions have more than one gods. People believed in hundreds of gods. For each phenomenon there was a god. Gradually we learned that having hundreds of gods is not an good idea. So we short listed and finally reached to conclusion to have very few or just one god. But along with god, we kept alive one evil personality, the Satan to justify bad deeds around.
Usually Satan is believed to have power to manipulate only humans. He can only make them follow him and influence human being for bad things to do. Otherwise God is in-charge of all physical universe. Satan have nothing to do with natural laws and creation and destruction of stars planets... Satan also do not have any powers to create any living creatures. Its the Great god's uniqueness. He is the owner of life and death.
This concept was fine for thousands of years.... But what should we do to this brain...it questioning as usual. Now we are facing a big fault in this idea of having only one god in hands. Its very hard to justify one god as a good lord of the universe When we see so much destruction around us being caused by nature. Human history is full of devastations of floods , earthquake , and pandemics. We human have been fighting against these diseases.We take these disasters as god's will, only when we have nothing to control or when we could not understand their cause and solutions. Millions of people died due to diseases which spread on large regions as pandemics.
"A pandemic (from Greek πᾶν pan "all" + δῆμος demos "people") is an epidemic of infectious disease that is spreading through human populations across a large region; for instance a continent, or even worldwide. A widespread endemic disease that is stable in terms of how many people are getting sick from it is not a pandemic. Further, flu pandemics exclude seasonal flu, unless the flu of the season is a pandemic. Throughout history there have been a number of pandemics, such as smallpox and tuberculosis. More recent pandemics include the HIV pandemic and the 2009 flu pandemic." (source:wikipedia.org)
Viruses are causing these pandemics. God created these creatures to spread diseases in human beings. Religious people justify these diseases by saying that God test human beings with these diseases.... If this is the case then viruses are the agents of god to test human beings and check if we stay contented with these conditions..... or go astray and look for solutions and quite God's test?
We fight against viruses and kill these godly creatures.... why?
If good lord is sending these creature to test humans then we should entertain them as guests from god.
Otherwise if we want to stay alive and cure the diseases then we should create another god for bad things to justify pandemics, people with Disabilities at birth, children suffering with chronic diseases, kids having pain infections with every seasonal changes.... etc. etc. etc.......
No offence this is just a suggestion :)
