There were vacuum tubes before transistors
The Colossus, the world's first programmable digital computer, was operational by 1944, utilizing vacuum tubes rather than transistors. Transistors were invented later, with the first practical transistor created at Bell Labs in 1947. Therefore, transistors were developed approximately three years after the Colossus was built.
Because - when Colossus was built (in 1943), microchips had yet to be invented ! Microchips replaced valves and transistors in newer computers.
