I don't know why you persist in these blatantly incorrect statements. But
to avoid the confusion that you have begun to generate, I will once again
quote the theorem:

An analog signal waveform may be uniquely reconstructed, without
error from samples taken at equal time intervals. The sampling
rate must be equal to, or greater than, twice the highest
frequency component in the analog signal.

Please read and notice the first four words "An analog signal waveform".
