user: Write a paragraph to refute a claim by a colleague that ancient structures such as Stonehenge, the Great Pyramid are evidence of UFO activities on Earth

assistant: There are several strong arguments against concluding that alien races built the structures like the Stonehenge or the Pyramids. First, there is evidence that these magnificent structures were built by humans. For example, tombs of the pyramid builders were found in the vicinity of the Great Pyramind (with human remains!). The technology to move and assemble the massive stones of the Stonehenge has been shown to be available to humans at that time. Second, given that space is vast the chance of finding one tiny planet among billions is infinitesimal. If alien intelligence had indeed found our one inhabited planet they are unlikely to have just created couple of structures and avoided any further contact with Earth and its inhabitants. In science, Occam’s Razor (“the best explanation is the simplest one”) is a guiding principle and until there is much more evidence of alien visitation it would be inadvisable to jump to a conclusion that aliens built these structures.

user: What is the etymology of the word cookie?

assistant: <think>
The word cookie dates from at least 1701 in Scottish usage where the word meant "plain bun", rather than thin baked good, and so it is not certain whether it is the same word. From 1808, the word "cookie" is attested "...in the sense of "small, flat, sweet cake" in American English. The American use is derived from Dutch koekje "little cake," which is a diminutive of "koek" ("cake"), which came from the Middle Dutch word "koke". Another claim is that the American name derives from the Dutch word koekje or more precisely its informal, dialect variant koekie which means little cake, and arrived in American English with the Dutch settlement of New Netherland, in the early 1600s.</think>
The earliest known usage of the work cookie comes from 1701 in Scotland, where it meant "plain bun".  Starting in 1808 the term was associated with small, flat, sweet cakes as part of American English, which is believed to be derived from the Dutch word keokie.

Tourism in India is important for the country's economy and is growing rapidly. The World Travel and Tourism Council calculated that tourism generated ₹13.2 lakh crore (US$170 billion) or 5.8% of India's GDP and supported 32.1 million jobs in 2021. Even though, these numbers were lower than the pre-pandemic figures; the country's economy witnessed a significant growth in 2021 after the massive downturn during 2020. The sector is predicted to grow at an annual rate of 7.8% to ₹33.8 lakh crore (US$420 billion) by 2031 (7.2% of GDP). In October 2015, India's medical tourism sector was estimated to be worth US$3 billion, and it is projected to grow to US$7–8 billion by 2020. In 2014, 184,298 foreign patients travelled to India to seek medical treatment.

Over 17.9 million foreign tourists arrived in India in 2019 compared to 17.4 million in 2018, representing a growth of 3.5%. This makes India the 22nd most visited nation in the world and 8th in Asia and Pacific . Domestic tourist visits to all states and union territories numbered 1,036.35 million in 2012, an increase of 16.5% from 2011. In 2012, National Geographic's Traveller magazine named the state Kerala as one of the "ten paradises of the world" and "50 must see destinations of a lifetime". In 2014, Tamil Nadu, Maharashtra and Uttar Pradesh were the most popular states for tourists. Delhi, Mumbai, Chennai, Agra and Jaipur were the five most visited cities of India by foreign tourists during the year 2015. As of 2017, worldwide, Delhi is ranked 28th by the number of foreign tourist arrivals, while Mumbai is ranked 30th, Chennai 43rd, Agra 45th, Jaipur 52nd and Kolkata 90th.

The World Economic Forum's Travel and Tourism Development Index 2021, which replaced its previous Travel and Tourism Competitiveness Report, ranks India 54th out of 117 countries overall. The last edition of the Travel and Tourism Competitiveness Report, published in 2019, had ranked India 34th out of 140 countries overall. The report ranked the price competitiveness of India's tourism sector 13th out of 140 countries. It mentioned that India has quite good air transport infrastructure (ranked 33rd), particularly given the country's stage of development, and reasonable ground and port infrastructure (ranked 28th). The country also scored high on natural resources (ranked 14th), and cultural resources and business travel (ranked 8th). The World Tourism Organization reported that India's receipts from tourism during 2012 ranked 16th in the world, and 7th among Asian and Pacific countries.

The Ministry of Tourism designs national policies for the development and promotion of tourism. In the process, the Ministry consults and collaborates with other stakeholders in the sector including various central ministries/agencies, state governments, union territories and private sector representatives. Concerted efforts are being made to promote niche tourism products such as rural, cruise, medical and eco-tourism. The Ministry of Tourism maintains the Incredible India campaign focused on promoting tourism in India.</think>
