I too agree that there must be a beginning for everything. But, 'anadi' here means 'no one really knows where and when it really started'.

Hence, no useful purpose will be served in researching things like these, as they will be only meaningless pursuits.

It is like this.

A person kept on digging a well, expecting water. But, even after going very deep, he could not find water.

Then only he realised that he could have stopped the pursuit and instead gone to some other location, for starting the same work afresh.

Thus he wasted much of his precious time and resources.
