No one has ever seen an atom.
Which is not too surprising, when you consider that the shortest wavelength of light
that our eyes can detect is more than 1,400 times the covalent radius (the "size") of
the largest atom. To see an atom in visible light would be like trying to feel the outline
of a mosquito by brushing it with a feeler the size of a person.

Ernest Rutherford was the man you are thinking of. He was the first person to 'split the atom'.
The first person to see cells was Robert Hooke in 1665.
The first person to see Jesus after he resurrected was Mary Magdalene.
The first person to see Jesus after his resurrection was Mary Magdalene.
Lucy Skinner James was the first person to see a water flea
The person who says "not if I see you first" is saying I'll see you before you see me. One person says" see u at the party" the other person says "not if I see u first". It just means the person saying "not if I see u first" will see you before u see them. Also means that they're planning to be there ( but they might not).
This is actually a pair: Person 1: See you at the party. Person 2: Not if I see you first. The implication is that if Person 2 sees Person 1 before Person 1 sees Person 2, then Person 2 will then approach Person 1 him/her.
