"countless articles out there confirm this."
No they don't. They discuss the difference in processing power - and how does rocket technology comparable to an iPhone? iPhones do not send astronauts to the moon. I swear to God you people think that society consisted of troglodytes rubbing sticks together in caves and hunter gathering prior to the invention of the smart phone.
If it's computing that you are referring to, you should have specified. Technology is a very broad term. Understand that Apollo on board computers had a performance comparable to the first generation of personal computers like the Acorn, Apple 2 and Commodore 64. The guidance computer had RAM of 4KB, and a 32KB hard disk). Their sole purpose was to take large quantities of numerical data and organise it into a more useful format. That original data was calculated by the main frames at NASA, and then beamed up to the spacecraft by radio telescope at the rate of 1,200 bits per second. They did not require he power for touch screens or to hold graphics etc like today’s smartphones.
The AGC was very compact and a brilliant piece of kit. What you people fail to understand is the fact that it was purpose-built, and did what was required incredibly well. It also could handle overloads by resetting itself without losing the instruction stack it had which was prewritten onto rope core memory, and would re prioritise those commands on the fly. IBM engineers also developed the mini integrated circuits that meant computers could be small enough to fit inside a rocket or spacecraft. It was a brilliant piece of technology for the time. You also likely had no idea, as alluded to, that this was supported on the ground by the Real-Time Computer Complex (RTCC) which was an IBM computing and data processing system at NASA's Manned Spacecraft Center in Houston. It collected, processed and sent to Mission Control the information needed to direct every phase of an Apollo/Saturn mission. It computed what the space vehicle was doing and compared that with what it should be doing. RTCC worked in real-time -- so fast, there was virtually no time between receiving and solving a computing problem. IBM 7094-11 computers were used in the RTCC during NASA's Gemini program and on the first three Apollo/Saturn missions. Later, IBM System/360 Model 75J mainframes, plus peripheral storage and processing equipment, were employed. Two computers were used during a mission: one was primary; the other operated identically but as standby. Why are you making what you assume to be authoritative comments about subjects that you have no knowledge of whatsoever?
"The astronauts even said so during a Q&A after"
That they did this with "less technology than an iPhone"? How remarkably sagacious of them back in 1969.

"The fact they supposedly did this just 60 years after the Wright brothers invented an airplane is laughable."
Why? You can progressively trace every stage of the technological development that culminated in the moon landings that made it possible. This is all documented.
"The command module supposedly reached 4,000 degrees upon re entry at a speed of 25,000 mph but yet it just miraculously slows down to almost nothing so parachutes float it down?"
Prior to reentry the speed of the CSM had exceeded 24,000mph. The service module was ejected and the command module performed a controlled double dip reentry using and ablative heat shield to withstand and protect the craft form the 5,000 °F temperatures generated by reentry. After entering the atmosphere, the acceleration built, peaking at 6 g (59 m/s²). This dropped as they slowed down due to aerobraking, and emerged from radio blackout. Passing through 7,300 metres (24,000 ft), the apex cover was blown by a pyrotechnic charge. This exposed the two sets of parachutes. First the two drogue parachutes were released, which slowed and stabilized the capsule from 310mph to 170mph. They pulled out the three large main parachutes some twenty seconds later which slowed the CM to around 22mph for the targeted splashdown zone in the Pacific Ocean.

It varied from mission to mission. On Apollo 8, the first mission to fly to the Moon in December of 1968, the S-IVB was put on a trajectory that had it fly by the moon before entering solar orbit. The S-IVB stages from the Saturn Vs that launched Apollo 10, the second mission that flew to the moon in May of 1969, and Apollo 11, the first lunar landing two months later in July, also were sent into a heliocentric orbit. Apollo 12's, as is now known, is currently orbiting the Earth. Look up J002E3. Apollo 13's became the first to be intentionally crashed into the moon - followed by Apollo 14. By Apollo 15, two ALSEPs (Apollo Lunar Surface Experimental Package) were on the surface of the moon to record the seismic impact. Apollo 15 also left an ALSEP on the Moon so when Apollo 16's S-IVB impacted on April 19, 1972 it was recorded by three seismometers. That crew also left an ALSEP on the surface, so when Apollo 17's S-IVB impacted on Dec. 10, 1972, the associated ground movements were recorded by four separate seismometers.

From memory, the dogs Veterok ("Breeze") and Ugoyok ("Little Piece Of Coal") were launched aboard Kosmos 110 by the Soviet Union in 1966 – as part of an evaluation of prolonged effects during space travel of radiation from the Van Allen Belts on animals between 1966 and 1969.
The U.S. launched three missions in the Biosatellite series. A total of six flights were planned. The first mission in the Biosatellite series, Biosatellite I, was also launched in 1966 I believe. The scientific payload, consisted of 13 select biology and radiation experiments containing a variety of specimens, including insects, frog eggs, microorganisms, and plants. Biosatellite II carried a biological payload similar to Biosatellite I. The primary objective of the Biosatellite II mission was to determine if organisms were more, or less, sensitive to ionizing radiation in microgravity than on Earth. In 1968 the first successful Soviet Zond ("probe") was launched containing a biological payload of turtles, wine flies, mealworms, plants, seeds, bacteria, and other living matter was included in the flight.
