JP Burger top-scored for Namibia
Namibian captain Deon Kotze urged his side to learn from a virtuoso batting performance from India's Sachin Tendulkar.
Tendulkar scored a magnificent 152, pacing his innings in difficult conditions early on before hitting out later.
Sourav Ganguly also scored an unbeaten 112 as India rattled up a massive 311-2.
Namibia lost by 181-runs, but Kotze called on his players to take positives out of the drubbing.
"It was a great pleasure to watch Sachin bat and I would like
our guys to learn from that," Kotze said.
"Sourav too was brilliant and when two quality players like them
get in, they are very difficult to stop.
"It was simply a case that we came up against the best batsman in
"We didn't field and bowl as well as we would have liked, but when Sachin is
batting like that, he is magnificent."
Namibia's batsmen, by contrast, failed to apply themselves in the same fashion as their Indian counterparts.
Jan-Berry Burger hit a six and four fours in his 29 and Kotze put on 51 with Melt van Schoor.
But only four of Namibia's batsmen reached double figures, with six of the wickets falling to part-time Indian bowlers Yuvraj Singh and Dinesh Mongia.
Namibia next face Ricky Ponting, Matthew Hayden and Damien Martyn when they take on Australia on Thursday.
