Hi everyone, how are all of you? I am a Muslim, but a few weeks ago I read the brain in a vat argument which for some reason placed many doubts on my mind. The brain in a vat story states that electrochemical stimulation from electrodes that mimicks bodily inputs could pass messages to your brain creating an alternate fake reality for you.

How do we know that we exist in the real natural world? Is it even possible for electrodes to create such electrochemical impulses that provide the brain with sensory & proprioceptive feedback? Thanks for your responses. I appreciate all clarifications.
