is interaction first or field?

[einstein_vishnu]

without the interaction we can't measure the field so interaction should come first which is against the literature.

Euuh, what do you mean.

In QFT fields are used in order to describe the interaction. The particles involved (both fermionic matter fields as well as bosonic force fields) are the quanta of these fields acquired by the second quantization.

don't think that the interaction generates the field. The interaction itself is described by the field.

There is no distinction between "interaction" and "field".

(That's really what marlon just said!)
