UFO（俗称飞碟），是UnidentifiedFlyingObject的简称，意指所有一切未经查明或者不可识别的飞行物；经专家、科学工作者鉴别，不可识别的飞行物体。这个词最早出现于上世纪40年代美国空军的调查报告中。

1947年6月24日，美国商人肯尼思-阿诺德驾驶私人飞机途经华盛顿雷尼尔山上空时，看到了9个发光的物体像碟子一样呈编队快速移动。这是现代人研究UFO的开始，但这并不是人类第一次看到不明飞行物，我国古代春秋时期的《山海经-博物志》中已有有关记载，以后历代史书都有这类UFO记载。19世纪沙俄时代的科学院也有详细报告。此外，各国家的史前遗迹、建筑、岩画、遗留物中也都有关于UFO的记载。1942年，一个外国人在天津街头拍摄了一张UFO的照片，这被专家认为是人类最早的一张UFO照片资料。按照几十万起UFO报告的现象可大致分为五类：一、对已知飞行物体或已知自然现象、已知生命物质，例如气球、飞艇、人造卫星火箭残骸、昆虫群、飞鸟等；二、特定环境下一些社会群体或个人的幻觉、心理现象；三、未知的自然生命，生物学家认为大自然中除了固态、液态、气态外应还有第四生命，但这点还未经证实；四、未知的自然现象，如地光火球、球状闪电、等离子体；五、人们不能制造、不能完全认识的智能飞行器或飞行物，也就是人们常说的“飞碟”、“外星人”。中国古代遭遇UFO的资料：苏东坡曾亲眼目睹据说那是在三国时期的吴国，一群玩耍的小孩中出现一个身高四尺，身穿蓝衣，长相很怪异的孩子。这个蓝衣孩子对其他小孩说，自己是火星人，因为看地球上的孩子玩得开心，所以才下来看看他们。还说将来天下要归司马氏所有。清朝画家吴友如画的《赤焰腾空》“是时江月初生魄，二更月落天深黑。江心似有炬火明，飞焰照山栖鸟惊。怅然归卧心莫识，非鬼非人竟何物？”（苏东坡《游金山寺》）不是鬼不是人究竟是何物？不说苏东坡当时夜游镇江的金山寺时，在月黑星稀的二更，忽见江中亮起一团火的奇遇深感迷惑，今人也是迷惑的。因为这样的景观今人看了还是无法给出准确的答案，而仍是猜测这样的不明物可能为UFO，即外星人。外星人之谜是当今世界的热门话题，其是否存在、究竟是什么样子等争执从来没尘埃落定过，但是从古自今，对那些被今人视为UFO的不明物，古籍、书画中有颇多记载。比如清代画家吴友如约作于1892年（光绪十八年）的画作《赤焰腾空》，就被人们认为是一篇详细生动的UFO目击报告。《赤焰腾空》的画面上绘有许多身着长袍马褂的市民聚集在南京朱雀桥头，仰望空中一团火球。吴友如在画面上方落款写到：中国古代UFO频频出现？“九月二十八日，晚间八点钟时，金陵（今南京市）城南，偶忽见火毯（即球）一团，自西向东，型如巨卵，色红而无光，飘荡半空，其行甚缓。维时浮云蔽空，天色昏暗。举头仰视，甚觉分明，立朱雀桥上，翘首踮足者不下数百人。约一炊许渐远渐减。有谓流星过境者，然星之驰也，瞬息即杳。此球自近而远，自有而无，甚属濡滞，则非星驰可知。有谓儿童放天灯者，是夜风暴向北吹，此球转向东去，则非天登又可知。众口纷纷，穷于推测。有一叟云，是物初起时微觉有声，非静听不觉也，系由南门外腾越而来者。嘻，异矣！”火球掠过南京城的具体时间，地点，目击人数，火球大小，颜色，发光强调，飞行速度等，吴友如在题记中都做了记载。《赤焰腾空》也被认为是中国最早关于UFO的图画之一，成为今人研究UFO的一则珍贵历史资料。其实早在东晋干宝的《搜神记》中，就记载过一件与火星人接触的故事。据说那是在三国时期的吴国，一群玩耍的小孩中出现一个地身高四尺，身穿蓝衣，长相很怪异的孩子。这个蓝衣孩子对其他小孩说，自己是火星人，因为看地球上的孩子玩得开心，所以才下来看看他们。还说将来天下要归司马氏所有。有个孩子跑去将此事告诉家中大人。当大人赶来时，火星人缩身跳到空中，只见一块白色的绢布拖着长长的带子向高空飞去。后来，火星人的预言得到了实现，果然是司马氏结束了三国鼎立的局面。另外，《宋史·五行史》记载，宋乾道六年，西安官塘出现了一高约丈余、鸡首人身的不明物，从高空而降，大白天在田野上行走，还试图与人交谈。《五行志》中也记载了清朝康熙十二年三月时，当时有人看到过一个黑面人在空中飞驰，红光闪闪的，如同在空中放火。官府捕快闻讯而来，想对其进行追捕时，黑面人忽然不见了踪影。这样看起来怪诞不经的事，在中国古代灿烂辉煌的历史文化中，确实有过不少的记载，为悬而未解的外星人之谜更加增添了神奇的色彩，也为后人研究外星人提供了宝贵的线索。MoviesPart1DialoguesFocus:IdentifyargumentsRecognizespecificdetailsMakeinferencesDialogue1
