I do not see the connection between all of our every day activities and "pointless existence". Do we eat because of a pointless existence, or because of dukkha?
Let's lay it out for clarity.
Buddhists teach men eat to avoid the suffering of hunger.
You can make more similar statements:
Men work to avoid the suffering of poverty, lack of resources.
Buddhists also teach that you needed to attack the root of the problem. If you determine you could do without a majority of those resources, you could avoid the problem of suffering caused by the lack. So if a person thought he needed to work extra hard or start a business so that he can buy an expensive car, if instead he removed the desire for the car, then he would neither have to work more nor feel depressed at not having the car!
So the statement:
Men work to avoid the suffering of poverty, lack of resources.
which explained a way to avoid suffering could be replaced in the life of the person experiencing that type suffering, like so:
Men analyse the phenomena of craving,
find a way to neutralise it,
to avoid the suffering of poverty, lack of resources.
So whilst unenlightened men fall prey to craving, which is a vicious cycle, enlightened men find a way to end that cycle.
Unfortunately, whilst eating to avoid dukkha is outright harmful (obesity, people!), or learning a martial art to fight off those who can harm you in combat, reflecting to avoid dukkha is also harmful.
All that needs to be known about God and his requirements of man can be seen in Nature .
Effort must result in gain. If animals are born from one womb, eat, rest, reproduce and disappear into another womb, of the earth, leaving nothing of benefit to themselves, then that one animal life was a waste. Of course as stated, animals aren't aware of the absurdity of their pointless existence, but men have it rubbed in their face all day.
Unless they are distracted into focusing on lesser issues.
Luke 12
4“I tell you, my friends, do not be afraid of those who kill the body and after that can do no more.
5But I will show you whom you should fear: Fear him who, after your body has been killed, has authority to throw you into hell. Yes, I tell you, fear him.
If a ruler appears and tells you you have been enjoying his protection for many years and now he needs you to pay taxes for the protection provided, you can't reply you've never heard of him. Ignorance of requirements is no defence against the requirement. Besides, the announcement explains why you were manufactured by that ruler, and opens up a whole new world of fulfillment to your existence.
Before that you had no answer to why you were given a slot in time and all you did never benefited you substantially, permanently.
I tried it for 30 years. It didn't bring me any closer to knowledge of God or of Jesus. What do you suppose went wrong?
A man went around the world looking for the most unique and most expensive treasure and found it only when he returned home.
If you asked God the question on the day of your auditing, he'd probably ask you why you never carried out the simplest of due diligences.
Pray.
This way.
"Give us this day our daily bread."
It wasn't Moses who provided bread, but God.
Jesus never upped his game by joining self improvement classes or hiring Schwarzenegger but by living on every word that proceed ed from God's mouth.
So ask for the bread from heaven.
And for the teeth to chew it with:
11What father among you, if his son asks for bread, would give him a stone, or if he asks for a fish,
k would give him a snake instead of the fish?
12Or if he asks for an egg, would he give him a scorpion?
13So if you who are evil know how to give good gifts to your children, how much more will the Father in heaven give the Holy Spirit to those who keep asking him!”
Allah - Wikipedia
Do you do what Allah requires, including praying towards Mecca?
"Allah" is misapplied in Islam. The mark of a good worldview is consistency. Islam majors in abrogation. That's why men love it, it tickles their ears. It reinvents itself every generation. More women after a war? Polygamise (I just invented a word!) the view/teachings.
I prefer to see it as being tried by fire, and persisting.
Unfortunately the world doesn't run on your preferences, just because you say so.
