Why we humans drink alcohol (science)

(Before Civilization) Ancient humans may have been drunk every single day

Ah, man, the Five Precepts say no drinking?

The Five Buddhist Precepts (Etsy)

The fifth of the Five Precepts the Buddha advised humans to adopt is to abstain from intoxicants that occasion heedlessness such as alcohol, drugs, and such substances [12, 13].

The Five Precepts (guidelines for morality, virtue, human ethics, harmlessness, ahimsa) are called pañca-sīla, binding on all Buddhist laypeople. They are to abstain and refrain from:

1. killing any living being
2. stealing (taking what is not given)
3. sexual misconduct
4. false speech (which means speaking falsehoods or lying and malicious speech, harsh speech, and frivolous speech or "animal talk"* mislabeled as gossip)
5. the use of intoxicants (such as beer and spirits or surāmeraya).

• Five Precepts or Training Rules (sikkhāpada)

Avoid doing all harm and be happy.

Early Buddhist texts nearly always condemn alcohol as do Chinese Buddhist later post-canonical texts (of the Mahayana tradition).

Smoking is sometimes also included here. In modern times, traditional Buddhist countries have seen revival movements to promote the Five Precepts, the least good karma if we hope to ever be reborn on the human plane again and avoid the subhuman planes.

What are the Five Precepts?

In the West, the precepts play a major role in Buddhist organizations. They have also been integrated into mindfulness training programs -- though many modern "mindfulness" specialists, having changed the definition of "mindfulness" (which the Buddha called sati) to something that better suits them -- do not support this because of the precepts' spiritual religious import.

Lastly, many conflict prevention programs make use of the precepts. More

What do we do when drinking other than "animal talk"?

Back off, Bich! - Don't call me 'bich,' Birdbrain!

*What is "animal talk"? It is lowly speech, literally "beastly talk," the name the sutras (ancient texts) give for the following: "Talk about:

• rulers and robbers [criminals in and out of office, like kings and robber barons],
• politicians and armies,
• dangers and wars,
• eating and drinking,
• fashion (frivolous clothing) and dwellings,
• garlands and scents (baubles and cosmetics),
• relationships (relatives),
• vehicles (chariots),
• villages and markets (real estate and shopping),
• towns and districts,
• women and heroes,
• street talk,
• gossipy talk by the well,
• talk about the departed from days gone by,
• tittle-tattle,
• talk [speculation] about [the origin of the] world and ocean,
• and talk about gain and loss" (A.X.69, etc.) 

In the Commentaries, four further kinds of low talk are enumerated, bringing the total to 32 varieties, namely:

1. talk about sensual enjoyment,
2. self-mortification (tapas, penances),
3. existing eternally (Eternalism)
4. self-annihilation (Annihilationism).
