If I may, arguing with atheist is pointless and not fruitful.
Atheist will change the rules of the discussion on a whim.
Atheist by simple definition means "a person who lacks belief in the existence of gods or deities"
Atheist does not mean they do not believe in God but rather they lack knowledge of God. i.e. An empty glass without drink in it or an empty plate without food on it.
The hypocrisy of atheism is this, although they, themselves claim not to believe in God, they sure waste a lot of time convincing others of their beliefs on something they claim does not exist.
The second part of their hypocrisy is , they indulge in many thing that originated by belief in God ; such as clothing, cleanliness, morals, rules, laws, governing-authorities, civilities, LOVE, HOPE, Mercy, Forgiveness, sharing, education-pursuit of knowledge(basically how science is defined), family matters(co-existing), ministry(medicine), Enlightenment(philosophy), They even claim "FAITH" in what they believe in errrr... what they do not believe in.
Most of what they claim as facts are still scientific theories.
What they do not understand, atheist call it the "UNKNOWN", funny that is how God's Knowledge of his Spiritual Word is define.
Most of their arguments are based on others works and not of their own input, basically plagiarism of others works as their own thoughts.
And boy they plagiarize it all ; stand-up comedy skits, movies, songs, poems, novels, A.I. (like their own fake intelligence), politics, religions, philosophies, ...etc.
This is a huge foolish-palette, they present as their OWN thoughts but underneath they are simply frustrated with everything in their lives but can never pin point what exactly motivates them.
The signature of atheist-ism is grasping at straw man, circle after circle they will present for anyone who does not agree with them to follow on their terms.
Should you find yourself in conversation with atheist, just treat them like the general unbelieving people that they are, nothing significant about them, and do not fall for their conversational traps that lead to their social arenas that they use to pacify their carnal-ignorant egos.
Know first, it is God who has them in this state of mind, and nothing can oppose the Will of God.
Psalm 14:1
To the Chief Musician.
A Psalm of David
. The fool has said in his heart, “There is no God.” They are corrupt, They have done abominable works, There is none who does good.
They are soiled children pointing at others in their arrogance, claiming "you all stink!", I would simply say "OK!?!" and move toward fresher air
