1st conditional (for present and future)
We use 1st conditional to say that something is possible after something else happens.
When a condition in the first part of the sentence ( ‚if‘ part ) happens, next thing follows ( will +…..).
You can’t use 1st conditional for past possibilities, we use 3rd conditional for that (see B2 section).
If + present simple, will……

We never use ‚if + will‘ in the same part of the sentence.
