Is there any technology existed before science?

Absolutely! Modern man (Homo Sapiens) have never existed without technology, the ancestors of modern man invented many technologies (e.g. edged stone tools, bone tools, fire making tools) that modern man improved on. Science in the modern sense has only existed for about 400 years. Modern man invented many technologies long before that by trial and error (e.g. metal working, brewing fermented drinks, cheese making, glass making and blowing, even a simple electric battery before 3000 BC).
