If the word atheist is fabricated, does that mean their love is also a manufacture of that error?

The Fishermen always use a net to catch the fish, because the fish can see water through the gap in the net and thinking there is nothing new to its observation gets trapped in the net. Had a covered bag been used to trap fishes, the fishes would never get in the trap as they can perceive it as something alien to what they normally observe. Applying this ogy to Atheists, does not the Satan use a similar net with the atheists fooling them with Rationality because Atheists always insists on proof of Allah (Subhaanahu Wa Ta’alaa)’s existence? I used this ogy in this context because Atheists get trapped with the concept that only what can be comprehended or observed with the eyes should be believed and what cannot should be rejected outright. They fail to realise that even LOVE cannot be seen with the Eyes but yet we know that it exists then why not Allah (Subhaanahu Wa Ta’alaa)?
