The earliest immigrants to North America found Indians already living there．The Indians numbered about 500,000 at that time．Their society was a primitive society,but they lived peacefully and welcomed the white strangers to the land．However,these early immigrants from Europe didn't want to share the land with the natives．They killed off many of the Indians,seized their land or pushed them off to lands farther away．Today the Indians,not more than half a million,live in poverty and misery on the land on which they were once masters. The earliest immigrants were the Spanish,who settled in the southern part of what is now the US．The next large group were the English,after the English came the French,Dutch,Irish,Germans,and other nationality groups,mostly European.

【正确答案】：B
【题目解析】：从文章的第一段可以了解到，早期的欧洲移民到北美时，发现已经有印第安人居住在那里。然而，这些移民并不想与原住民分享土地。他们杀害了很多印第安人，夺走了他们的土地或者把他们赶到了更远的地方。这些行为表明了移民的意图，即想要占领土地并据为己有。 A选项“他们认为印第安人不友好”在文章中并没有提及，文章中明确提到印第安人和平地生活并欢迎白人陌生人。 C选项“因为北美首先是由印第安人发现的”显然与事实不符，且文章没有提及这一点。 D选项“因为印第安人喜欢向白人宣战”也是错误的，文章中没有提到印第安人有这样的行为。 B选项“他们想要把土地占为己有”与文章描述的行为相符，是最合理的答案。因此，答案是B。
