文明史就更多了,人类以前地球上曾经有过智慧的物种也可以想象嘛
够进化N回了吧 |

life must take a long time to evolve to complicated enough to have a
creature like human being, so N times is too much. I admit time maybe
enough for a intelligent life to develop a couple of times, but that does
not mean it really happened that way. We need solid evidance to prove it.
otherwise, it is at the level of fiction.

maybe. why it is not just a freak ape? even intelligence life has
evolved for a couple of times, why it must be in the form of human
being?

A**z 发帖数: 184 | 6 我觉得可能性不大,如果对200万年前的情况一无所知倒是
可以进行这样的怀疑。现在的情况是,对于生物进化的历史,
还是有一套比较完备的证据的,这个可以上溯到十几亿
年前,数量级上与地球的年龄可比,而这个过程,从大趋势
上看,是从简单到复杂,没有反复。人类作为生物进化的
顶峰,也有不少的证据存在,如果说人类是从那些简单
生物进化来的,这个假说还是有相当道理的,化石,解剖学,
遗传学的证据也非常多。如果这个假说真的是事实的话,
我想现在这个文明,应该是地球上的第一次。
以上是以没有外星智慧生物到过地球为假设的,如果
他们曾经到过并且在这里建立一个新文明的话,就很难说了。

h**p 发帖数: 147 | 7 basically agree that the tandon't post is intersting, but it is
really G******, see this kinf of article too many times, but it
may be nice to some newcomers to see them, but I think it is very
good for those who point out the false(or not true)part, beside
i suugest that if ppl have time, go see the discoery channel,
the programs are widely coverd and very intersted, and most of all,
more precisely, at least they base on fact, (enough fact to make
a conclusion)
