Alcohol comes from the Arabic "al-kuhl" which was the name of a body-eating spirit. In fact, the English "ghoul" comes from the same word.
When Arab alchemists' ingested alcohol their senses deadened and they named the substance according to its "body-taking" qualities. Knowing this, European speakers who understood its etymology coined the use of the term "spirits" for alcohol.
The use of the term spirits for alcohol goes very far back so it's impossible to know for sure due the lack of written evidence, but this is the simplest answer to the question, and, in my opinion, the most likely to be true.
For every real thing that God has for us there is a counterfeit, the Bible says be not drunk with wine but be filled with the Spirit. When you are filled with God's Holy Spirit, it lifts you up , encourages you , gives you abilities that you don't possess with in your self, and when all is said and He adds no sorrow. The family and friends remain! He brings the peace you are looking for!
Because when you drink alcohol you become vulnerable to the after world. The veil is lifted and lost souls can possess you. You may even say or do silly/crazy things.
Is every one on this site retarded or alcoholics...liquor does consume you if you let it ..spirits means "breath"..."life breath"...it relaxes otherwise tense and up-tightness...therefore you may become a little vulnerable , or have less clarity in "the norm" it's like you kinda go to a level of existence different from the reality of non-alcoholic reality. In some ways your senses heighten...and in some instances it digresses...thus making it a bit harder to distinguish reality from fiction...or fantasy.
It is a distilled water which contains 35 percent alcohol
Because if you drink enough of them you think you can see spirits ???
