i will keep this polite in the effort to show there is nothing personal here, i am only interested in what can be proven to be true

the burden of proof is with the person making the claim. you have a claim that covid is real & is the cause of your illness & i am asking you to prove that claim is real

the vast majority of people may accept that covid exists & that is indeed a virus. firstly, i see you are speaking for others, this discussion right here is between you & i, if others wish to discuss this then it will be between myself & them so that no one is speaking for someone else. secondly, i am asking for what you have proven to exist, not what you accept to exist. thirdly, you are using an argumentum ad populum fallacy or appeal to masses fallacy, just because many people accept something exists is not proof that it exists

the vast majority may include highly educated people in pertinent fields, this is an argument from authority or appeal to authority fallacy, so as this discussion is between you & i, what proof have got from these highly educated people in pertinent fields that you have verified & you can provide to me so i can also verify that proves your claim?

the vast majority may also include people who have gotten ill or affected in some way, you are making a presupposition that the virus was the cause of this illness. as this discussion is between you & i, what proof do you have that i can also verify that the virus you are claiming was the cause of your illness?

there is no need to quantify “vast majority" because it is an argumentum ad populum fallacy or appeal to masses fallacy.

i am not making a claim, you are claiming covid exists & i am asking you to prove it exists. you are trying to shift the burden of proof; this is another fallacy. the only one making a claim in our discussion is you & i am asking you to prove your claim is real

so is conventional knowledge something that has been accepted or been proven? i am asking you to prove your claim is real

i have not investigated the flat earth topic & it is off topic to our discussion here, i want go as far as saying you’re using a red herring fallacy. you & i can discuss it further if you want in another thread, but my initial thought would be that the vast majority of the civilized world believes the world is round is the claim being made. i do find it interesting that you used the word believes though

there is no argument, you & i are discussing a belief you have that you claim is real & i am asking you to prove that belief is real

i feel i have been more than generous is pointing out your fallacies & faulty reasoning. i hope if our discussion continues it can progress forward based on logic & the proof you are able to provide
