Offcourse we should not. Infact there are many intresting bits and pieces that I've came across about European sea-faring but won't disclose them untill I've a reliable source to share with you.Then we might not call it a European trade network either. It was global after all, everyone got dragged in eventually.
But going by the scanty available information we can assume that it was Indian who were the first explorer of this trade network. Indian products were travelling in both of the directions so it's obvious that Indian people were travelling with them.
