"Then they said, 'Come, let us build ourselves a city, with a tower that reaches to the heavens, so that we may make a name for ourselves'" (Genesis 11:4) 

These were the words of men who planned to build the Tower of Babel.  There was every reason why their plans should succeed.  They had the know-how.  They were all of one mind and they had a common purpose - to accomplish something lasting in life, something that would outlive them.

There was a strange old man named Noah.  He built an enormous ark while people laughed at him for years.  But he didn't care.  He was working under orders - and he was not concerned that he might have looked ridiculous.

The Tower of Babel was a failure.

The Ark became an instrument of success and salvation

Perhaps the difference in accomplishment stemmed from the difference in incentive - "Whose name was at stake?"

"I am the LORD, that is My name; I will not give My glory to another, Nor My praise to graven images" Isaiah 42:8.
