Well that's just stupid. For several reasons. You have no land units, no defensive units, and no raiding units to apply immediate pressure - and immediate pressure is exactly what you should be doing against a bomber first type build.
Okay, the scenarios where you are likely to see a bomber are as follows:
1. 1st Air Bomber
He will do Pgen, Afac, Bomber... This results in an extremely early bomber, and you will likely only have 5 units and one factory operational.
2. 2nd Air Bomber
He will do Lfac, 2 Pgen, 2 Mex, 4 Pgen, Afac, Bomber... This is the more usual arrival time, and this is more popular with most players. As it allows for decent ground expansion and is a good compromise.
In either of these cases, you should IMMEDIATELY stop whatever it is you thought you were doing and take the following actions simultaneously:
- Build an Interceptor if you have an air factory;
- Build 2 or more T1 MAA from the land factory;
- Build static AA in your base with ACU; and
- Send all your land units to attack his expansion points (because he is very likely to have undefended engineers).
Now the first problem is that if you are letting him kill all your engineers, power, and storage, you are not adapting to the situation. Early bomber is an imminent threat. You must deal with it immediately. The second problem is that you are ill equipped to counter attack, because, you have no aggressive ground units of any kind.
