Any life smarter than us somewhere in the universe may have decided to leave us alone because it would be detrimental to our existence to show us our inadequacies.
We do know when time started – the big bang was 4.57 billion years ago, our Sun is about 40 million years old. My dad had a Vauxhall Viva back in the 70s with the original date-stamped log book – and it had not been clocked.
I think the Sun is a tad older than that
