The first computer program was written before the first computer was made

Explanation

Charles Babbage sketched the first documented computer program in 1837 for his Analytical Engine, a mechanical design that was never completed during his lifetime. Similarly, Ada Lovelace published a famous algorithm for the same machine in 1843, which is widely considered the first published computer program. These programs remained theoretical until electronic computers capable of running them were developed nearly a century later in the 1940s.
